Description

Emergency braking interfering system and method before collision
Technical field
The present invention relates to the automobile safety system technical field, refer to particularly the front emergency braking interfering system of a kind of collision and method.
Background technology
Along with the rapid growth of automobile pollution, the road traffic environment problem has become the major issue of national governments and social concerns.Japan's traffic accident analysis result shows in the front shock relatively high at proportion, because chaufeur error in judgement and the accident that the manipulation error causes have accounted for 46% of total number of accident.Same Japanese traffic accident analysis result show 39% traffic accident be can be correct at chaufeur take avoid the collision measure, as step on braking, beat steering handwheel collision has just occurred before.Simultaneously due to the chaufeur mistake, estimate difference and adhere under condition the safe stopping distance of (as ice and snow road, ponding road surface, good cement concrete road etc.), cause the accident bumped from car and the place ahead target also to account for significant proportion.
When from car and front truck or the place ahead obstacle during in being in danger of vehicle distance, the chaufeur in the high-pressure state particularly new hand's chaufeur is easy to maloperation, will speed up pedal as brake pedal.In this case, for the vehicle that carries the pre-collision system of tradition, when pre-collision system sends the instruction of emergency braking to brake system, driving engine still can increase moment of torsion, improve rotating speed.Therefore increase the stopping distance of automobile, increased the possibility of collision, aggravated the wearing and tearing of tire and brake clamp, aggravated the wearing and tearing of vehicle drive system, when engine torque and brake torque are all very large, even can destroy the driving system of vehicle.
Existing urgent anti-collision system comprise environmental sensor as trailer-mounted radar and/or vehicle-mounted camera, vehicle sensors as car speed sensor etc., controller and actuating unit as driving engine etc.Owing to can not selecting safety distance, and when emergency braking, if the chaufeur maloperation will speed up pedal as brake pedal, driving engine still can accelerate and increase to turn round, so not only increase stopping distance, also strengthened the possibility of collision, aggravated the wearing and tearing of tire.
Summary of the invention
Purpose of the present invention will provide emergency braking interfering system and method before a kind of collision exactly, this system and method can reduce emergency braking to the destruction of driving engine and car transmissions, shorten emergency stopping distance, greatly improve vehicle safety in motion.
