Problems solved by technology

[0006] However, the automatic braking function, or active braking function, can only actively prevent the vehicle itself from colliding with obstacles in front, or reduce the consequences of collisions, but cannot avoid the risk of collisions between vehicles coming from behind the vehicle.

Abstract

The invention discloses a vehicle automatic brake device and a method thereof. The device comprises a front detection module, a rear detection module, a control module and a brake module, wherein the front detection module is used for calculating collision occurrence time (T-front) of a vehicle and a front obstacle; the rear detection module is used for calculating collision occurrence time (T-rear) of a backside vehicle and the vehicle; the control module is used for receiving a vehicle speed signal and a vehicle brake pedal signal; when the speed of the vehicle is smaller than or equal to a speed threshold value (V1), the control module is used for controlling the brake module to perform complete brake and partial brake on the vehicle according to the collision occurrence time (T-front) of the vehicle and the front obstacle calculated by the front detection module, the collision occurrence time (T-rear) of the backside vehicle and the vehicle calculated by the rear detection module and the vehicle brake pedal signal.

Description

technical field [0001] The invention relates to the field of motor vehicles, in particular to the field of automatic braking of motor vehicles. Background technique [0002] In the prior art, many automobile manufacturers equip vehicles with an automatic braking function to avoid collisions between the vehicle and obstacles in front of the vehicle or reduce the consequences caused by collisions with obstacles in front of the vehicle and improve safety performance. [0003] The automatic braking function refers to a function that the vehicle can drive normally under the condition of non-adaptive cruising, such as when the vehicle encounters a sudden dangerous situation, it can actively generate a braking (or braking) effect to slow down the vehicle, thereby improving driving safety. technology. Most of the rear-end collisions occurred during urban road driving or low-speed driving. Drivers are prone to rear-end collisions due to distraction or paralysis at low speeds. [0...
