Problems solved by technology

[0016] However, adding a wired link W2 (or W3) between the sensor 20 located in the door handle and the BCM 10 is accompanied by integration issues due to the limited space in the handle and connection and cost issues for the BCM 10 since in order to include The handle model of the LED should change this BCM10 specifically, and therefore the general BCM common to all handle models can no longer be considered

Embodiment Construction

[0052] has been explained earlier figure 1 and 2 .

[0053] exist image 3 A two-way communication device according to the invention is shown in . The BCM 10 sends the light emission control signal of the LED LED1 to the sensor 20 through the supply line W1.

[0054] The communication from the sensor 20 to the BCM 10 via the supply line W1 is unchanged from the prior art. That is, the detection of the approach of the user's hand by the electrode 23 generates a detection signal, which is sent by the microcontroller 22 of the sensor 20 to the BCM 10 through the supply line W1.

[0055] In order to enable communication from the BCM 10 to the sensor 20 for controlling the activation of the actuator (LED1 ) located in the sensor 20 , the invention proposes to add a control signal generator 40 at the output of the microcontroller 11 of the BCM 10 . The command signal generator 40 comprises a switch S4 (for example in the form of a transistor) and a resistor R2 connected to the ...

Abstract

The present invention proposes a device for communicating between a microcontroller (11) of an electronic module (10) and a microcontroller (22) of a sensor (20), which is supplied by the electronic module (W1) via a supply line (W1). 10) power supply, and: the electronic module comprises a control signal generator (40) which generates a control signal modulated by a voltage on the supply line, the sensor comprises a control signal conditioning device (30) connected to the supply line, It comprises: a high pass filter (FPH), a voltage limiter (LT), an open collector output (CO), configured such that the control signal at the output of the control signal conditioning device is a voltage signal of constant average value and is Included in the supply voltage window of the sensor's microcontroller.

Description

field of invention [0001] The invention relates to a communication device between an electronic module and a sensor. More specifically, the invention proposes a communication device between an electronic module on board a motor vehicle and a sensor remote from said electronic module and located on said vehicle. Background technique [0002] Motor vehicles today include multiple electronic modules that control various sensors and / or actuators located on the vehicle. Certain modules manage the sensors and / or actuators of the engine block. They are called ECU (English for "Engine Control Unit (Engine Control Unit)"), or engine control unit. Other modules manage the sensors and / or actuators located on the vehicle body, they are called BCM (English for "Body Control Module (body control module)"), that is, with the sensors and / or actuators located on the vehicle body associated control modules. The BCM then manages, inter alia, sensors located on the vehicle's door handles th...
