Problems solved by technology

[0005] However, in the case of ECU failure, the internal pressure of the throttle body on the intake side will increase due to the sharp increase in engine speed, and the internal pressure of the brake booster connected to it will increase and the vacuum degree will decrease. As a result, the relatively sufficient braking force required for braking work cannot be obtained, which may further cause large-scale traffic accidents

Embodiment

[0111] When the booster control unit 120 receives the brake signal, if the vacuum value of the booster vacuum sensor B is low, it records a low vacuum event. The booster control unit 120 can output a warning message prompting to check the brake system when the number of recorded vacuum value drop events exceeds a certain number of times.

[0112] Warning messages can be transmitted to the driver's smartphone via a wireless communication module. When the driver's smartphone receives the warning message, it can use the GPS module to measure the location of the vehicle and recommend the repair center closest to the measured location by searching the repair center database.

Abstract

The invention discloses a brake device and method in which a booster control part provides backup control for an ECU. Including: a fuel pump (10), used to supply fuel to the engine; an engine vacuum sensor (A), used to monitor the vacuum state formed in the engine; an electronic throttle system (ETS, Electric Throttle System, 20), used to It is used to adjust the amount of air flowing into the engine; the electronic control unit (ECU, 110) is used to output the engine control signal for controlling the fuel pump (10) and the electronic throttle system (ETS, 20); the vacuum booster (40), used to utilize the vacuum state of the vacuum pump (50) to promote the pedaling force of the brake pedal (30); the vacuum pump (50), used to form a vacuum state in the vacuum booster (40); the booster vacuum sensor (B) , for monitoring the degree of vacuum formed in the vacuum booster (40); the control unit (120), for receiving the input of the vacuum value of the booster through the booster vacuum sensor (B) and controlling the vacuum pump (50) .

Description

technical field [0001] The present invention relates to a kind of brake device and its method that the booster control part provides ECU with backup control, especially relates to a kind of brake system that can ensure the normal operation of the brake system even in the case of a car rushing. A braking device and method thereof are provided for backup control. [0002] In addition, the present invention relates to a device and method for improving braking safety by enabling the control part of the booster to perform a backup function even in the event of an ECU failure, and more particularly relates to a In the case of an emergency acceleration failure caused by an ECU, the braking device and its method can also ensure that the braking system will not lose its proper function and make the braking system work normally. The booster control part provides backup control for the ECU. Background technique [0003] The vehicle's braking system is used to slow down the engine and ...
