5 .. Overview Introduction HVAC (heating, ventilation, and air conditioning) is the technology of indoor and automotive environmental comfort. These days HVAC systems are available in most of the mid and high end automotive. Traditional HVAC systems were mostly electromechanical with mechanical knobs to adjust air flow vents, cooling control, blower speed etc. MPC560xS/MPC565S based HVAC system is designed to replace existing mechanical switches based system with TFT LCD and resistive touch based interactive system. The HVAC design comprises all the basic features of HVAC system and adds some user friendly advanced features for better controllability. Figure. Block Diagram of MPC560xS/MPC565S based HVAC system.. Application Features and Components The Reference design features can be divided into two categories: basic and advance features.... Basic Features Airflow Vent Control The design consists of the five basic air flow vent control icons on the TFT LCD screen instead of mechanical rotator switch. The placement of icons gives the comfort of choosing any particular vent position in a single tap/ key press. Heating, Ventilation, and Air Conditioning (HVAC) Solution Rev. 0, 08/05 Freescale Semiconductor, Inc. 5

6 Blower Speed Control (5 Level) A five stage blower speed selection is provided on the screen. On tapping/key press an enlarged screen pops up to ease the selection even from rear-seat. The speed control could be implemented as analog control with very fine step size but is currently limited to five steps for comfort of user in switching from mechanical systems to advanced TFT LCD based systems. Cool/Warm Control An analog slider is implemented for the cooling control. On tapping/button press, similar to speed control, cooling control slider also enlarges and eases the selection. The analog slider is kept analogues to slider control in traditional mechanical systems but step size can be reduced to a much larger extent in advanced system. Defogger On/Off Recirculation On/Off Air Conditioning On/Off Defoggers, Recirculation, AC on/off icons are implemented as toggle switch for respective functionalities.... Advance Features In order to take the HVAC technology further closer to comfort and luxury various advanced features are implemented in the design. Four pre-defined intuitive profiles User defined profile(s) A typical HVAC system requires multiple inputs from user every time user turns on the system. These inputs are mainly driven from the climate condition at that time. Moreover, once the outside climate changes HVAC system needs to be reconfigured. To save the user from this activity time and again the advance HVAC design consist of four pre-defined profiles. These profiles can be intuitively chosen based on climate condition. These profiles are named as Sunny, Partly Cloudy, Cloudy and Rainy. Each profile automatically configures the HVAC system based on its predefined parameter. User is allowed to make changes in HVAC control even when a particular profile is selected. However there is another profile defined as User profile for customized settings. Once the settings are made after entering the user profile, settings will be saved and will be recalled on revisiting the profile. The profile auto saves the settings on each exit of the user profile. Cabin temperature display Date display Time display There is a cabin temperature display on the screen which gets the feed from temperature sensor. The design displays and maintains date and time information. The clock provided is of fair accuracy as per automotive standards. A user friendly GUI allows the setting of date and time in case of system powered-up for the first time or battery is re-installed.

7 Low power mode Low power mode has been implemented to conserve the battery. Application is designed to enter this mode, when the engine is not running. System control interfaces o IR remote control o Resistive touch control o RF remote control The trend of chauffer driven car has fuelled the thought of providing multiple ways to feed the input to the system. It could be simply touch, IR remote or RF remote (Current software provides resistive touch and IR remote capability only, though the hardware supports all the user interfaces), thus enables the rear seat passengers to control the system. Actuator motor stall detection Blower motor stall detection The traditional HVAC systems are reported with failures of overheating due to blower motor or actuator motor jamming. Electromechanical systems had no way to detect the jamming of motor. Driving such motor(s) resulted into burning of resistive elements, motor coils sometimes even leading to fire to the whole vehicle. The advanced HVAC design allows the detection of stall on blower and actuator motors. Upon detection of stall it stops driving the motor and thus saves the system from damage. Parking assist camera mode The system comprises of rear view camera feature which assists in driving the vehicle backwards or during parking. When the driver pushes the gear stick to reverse position, the rear view camera is switched on, whose video can be seen on the TFT. Currently the situation is simulated by a key press on IR remote. LIN and CAN for communication Communication interfaces like LIN and CAN are provided in the HVAC system, if it requires communication with body modules or engine control units etc. in future. Audio warnings for hazard reporting The system reports the hazards such as blower motor jam etc. in the form of Audio warning to alert the driver and passengers of the faulty condition in the system. QSPI memory for high end graphics SPI Memory is provided for high end graphics storage and parallel data bus (x or x8), allowing rendering graphics on the screen directly from QSPI memory. Scalability The design is highly scalable since the same hardware can be utilized for mid and high segment vehicles. A high segment vehicle could use complex graphics using the same platform (using QSPI memory) with all system control interfaces while mid segment vehicle could utilize relatively simpler graphics with one or two system control interfaces (remaining interfaces need not to be populated). This reduces the development cost and time for an OEM. Heating, Ventilation, and Air Conditioning (HVAC) Solution Rev. 0, 08/05 Freescale Semiconductor, Inc. 7

MC_HVAC MC_TOP MC_SSAVER MC_CLKSET MC_BLOWER MC_TEMP MC_CAMERA Heating, Ventilation, and Air Conditioning (HVAC) Solution Rev. 0, 08/05 8 Freescale Semiconductor, Inc.

39 ... MC_HVAC Movie Clip This movie clip displays and manages the graphics for following features: Vent control Defogger control Recirculation control Profile control Fan control ON/OFF control Cool/heat control This movie clip also checks periodically if any user input either by touch or IR remote has been detected. Upon detection the corresponding action is reflected back on screen.... Vent Controls The five vent controls which are typically available on mechanical knobs are placed on TFT LCD screen. Below is the snapshot of the five vent control icons. The icon highlighted indicates the mode user has selected. Figure 7.

The control is implemented as toggle switch. Highlighted mode indicates that user has switched on the defogger unit and vice versa. Figure 8. Graphical Interface Heating, Ventilation, and Air Conditioning (HVAC) Solution Rev. 0, 08/05 0 Freescale Semiconductor, Inc.

The control is implemented as toggle switch. Figure 9. Graphical Interface Heating, Ventilation, and Air Conditioning (HVAC) Solution Rev. 0, 08/05 Freescale Semiconductor, Inc.

42 ... Profile Control The profile selection is an additional feature given in the advance system as compared to a conventional system. Once a profile is selected based on profile predefined settings airflow vent, blower fan speed, cooling control takes position. The profiles icons are quite intuitive and can be easily chosen based on climate. It has five profiles described below. Sunny Partly cloudy Cloudy Rainy User defined Sunny profile forces vent position for air on face and foot. It maximizes the blower speed (speed ) with maximum cooling.
