Abstract

The invention discloses an auxiliary system and an auxiliary method for emergency brake. The auxiliary system comprises a body control module BCM unit, a vehicle speed sensing unit, a distance sensing unit, an ABS (anti-lock brake system) unit, a first speed reducing unit, a second speed reducing unit and a brake switch; the body control module BCM unit is used for detecting starting signals of the anti-lock brake system ABS unit, instructs to start the first speed reducing unit when the original running speed higher than the preset speed is changed into the running speed of zero and instructs to start the second speed reducing unit when the distance from a vehicle to a front obstacle is smaller than a preset value; the vehicle speed sensing unit is used for detecting the vehicle speed and change of the speed changed from the original running speed to zero; the distance sensing unit is used for acquiring the distance from the vehicle to the front obstacle; the ABS unit is used for being started when the brake switch is closed; the first speed reducing unit is arranged at the tail of the vehicle; the second speed reducing unit is disposed at the head of the vehicle; and the brake switch is used for changing the running speed value into zero when closed. By the auxiliary system and the auxiliary method, external resistance can be effectively increased when the vehicle is braked in emergency, and braking distance is reduced, so that running safety is improved.

Description

technical field [0001] The invention relates to automobile safety technology, in particular to an auxiliary system and an auxiliary method for emergency braking. Background technique [0002] With the increasing popularity of automobiles, driving safety has attracted more and more attention from car owners, and car safety performance has become the primary consideration for most prospective car owners when purchasing a car. For the safety of automobiles, several aspects that are usually paid attention to are: whether the number of airbags is sufficient, whether the steel plate of the body is thick enough, whether there is an electronic stability device (Electronic Stablity Program) including anti-lock braking system ABS and driving anti-skid system ASR , ESP), and so on. [0003] However, another factor that poses a great hidden danger to driving safety, the braking distance, has not received enough attention at present. Braking distance refers to how far the car still nee...
