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 invention proposes a device for communication between a microcontroller (11) of an electronic module (10) and a microcontroller (22) of a sensor (20), the sensor being supplied with current by the electronic module (10) via a power supply line (W1), and: the electronic module comprises a control signal generator (40), which generates a control signal in modulation voltage on the power supply line, the sensor comprises a device for regulating the control signal (30), connected to the power supply line, which comprises: a high-pass filter (FPH), a voltage limiter (LT), an open collector output (CO), arranged such that the control signal at the output of the device for regulating the control signal is a voltage signal of constant mean value and included within the supply voltage window of the sensor 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 ECUs ("Engine Control Unit" in English), or engine control units. 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 that detect approaching...
