Automotive CAN gateway module

Transcription

1 Function The compact vehicle suitable CAN gateway module with PLC and soundfunction is to easily extend existing vehicle functions with low wiring costs. It is freely programmable and equipped with three CAN interfaces. Thus it is possible to activate functions in the vehicle directly via CAN. Through the OBD connection and free programming other functions are programmable. Several vehicle CAN protocols are available on request. Application Examples: Transfer of vehicle secondary functions (e.g. wheelchairs) Vehicle customizings, which data from the CAN-bus receive or activate functions via CAN Additional control points in vehicles (e.g. driving Schools) Vehicle customizings for construction equipment Housing and connector dimension: 89 x 95 x 35 mm connector: 3 x 18-pin Molex Mini Fit Junior 3D view 1

2 Data exchange: Bus system For the data exchange are the following bus systems available: 3 x CAN high speed according to ISO or optional with 1 x CAN high speed and 2x CAN low speed Technical Data: operating temperature: -40 C up to 85 C voltage range: 9-18 V protection class: IP53 EMC: 2009/19/EG e1 approval number: analog input (digital usable) 4 digital HSD outputs potential free relais soundmodule (bleeperfunction) each HSD output max. 2,5A at t amb <80 C each relais output 3A Freescale HCS12XEQ processor with flash-technology (optionally multiprogramming) 3 x CAN high speed or optional with 1 CAN high speed and 2 CAN low speed o : CAN0: CAN-HS with 120Ω load resistor CAN1: CAN-HS without load resistor, e.g. connection with existing CAN-bus CAN2: CAN-HS with 120Ω load resistor o : CAN0: CAN-HS with 120Ω load resistor CAN1: CAN-LS CAN2: CAN-LS compact housing (85 x 95 x 35 mm), connector 3 x 18-pin Molex Mini Fit Junior. thanks to its powerful processor, the module is CANopen- und SAE J1939- able 2

3 Programming A Freescale HCS12 processor with flash-technology is used, which can be programmed a number of times. Two methods of functional programming: 1. Graphical programming with MRS Developers Studio, the integrated softwaretool CANgraph and suitable flash-programming-tool. 2. Programming with a C-development system e.g. Codewarrior. Advantages of graphical programming with MRS Developers Studio There is no need for detailed knowledge of the microcontroller and a programming language. This system provides pure graphical programming of the controller. The acquisition and training costs are very small. Preference: With graphical programming the possibilities of bus communication are limited. Advantages of programming with a C-development system Very complex as well as user specific functions can be realized. Preference: An extensive knowledge of C-programming, the HCS12 microprocessor and the circuit is absolutely necessary. Options communication slot-expansion with radio module e.g. bluetooth to SCI to operate functions wireless 3

4 Hardware Connector: 3 x 18-pin Molex Mini Fit Junior Supply: Controller supply: 9 18 V The module is protected against reverse polarity and electrical transients. The module has a Quad-Highside-Driver and potential free relay outputs. The quiescent current is less than 1mA (Stand by). The power consumption without load at the outputs approx 40mA. Power-on: The module can switched on with the ignition signal at KL15 or CAN-bus, then it keeps itself through the MC/Power Signal. Inputs: The module has 20 analog inputs. These are 0 30 V inputs ans can be used digitally to 30 V. Outputs: Quad Power-Highside-Driver (Type VNQ5050AK oder VNQ5050), overload and short-circuit protected with a digital status load. The status can be used to detect an open load or overload condition. At 80 C environment temperature each channel can supply up to 2,5A. 4
