Control system, abs/esp controller, body controller and corresponding method

Abstract

The invention discloses a control system, an ABS / ESP controller, an automobile body controller and a corresponding method. The ABS / ESP controller comprises a judging module and a control module, wherein the judging module is configured to judge whether an active brake booster is in preset brake pressure state or not, and the control module is configured to control the connection and disconnection of a brake pedal switch and the automobile body controller, and / or send a restrain brake lamp control signal to the automobile body controller when the active brake booster is in preset brake pressure state. The restrain brake lamp control signal is used for controlling the brake lamp not to light when the automobile body controller receives the restrain brake lamp control signal. The invention solves the problem that the brake pedal generates a little displacement to make the brake lamp mistakenly light in case the driver fails to operate the brake pedal when the active brake booster is activated.

Description

technical field [0001] The invention relates to the field of automobile brake lights, in particular to a control system, an ABS / ESP controller, a vehicle body controller and a corresponding method. Background technique [0002] With people's increasing requirements for car driving safety, it has become a trend and standard to configure ABS / ESP system. At present, the active brake booster technology has been applied in the ABS / ESP system, but the application of this technology also brings certain problems. Since this technology uses the ABS / ESP system to automatically control the active brake booster and build up the brake pressure in advance when the driver does not step on the brake pedal according to the current vehicle operating conditions, when the ABS / ESP system intervention condition is reached, Brake output to the vehicle. Therefore, after the active brake booster is activated, the brake pedal may be slightly displaced when the driver does not operate, and then the ...

AI Technical Summary

Problems solved by technology

[0004] The current technology is to reduce the effective range of the brake pedal as much as possible by pre-calibrating the position of the brake pedal to prevent its effective value from falling into the misjudged travel area, but this cannot solve the problem of accurate lighting of the brake lights. Reduced brake pedal control sensitivity for brake lights

Since the pressure of the active brake booster changes dynamically, the amount of displacement of the brake pedal also changes, so even if the effective range is calibrated, the occurrence of misjudgment cannot be ruled out.
