Embodiment Construction

[0015] As mentioned above, in particular, the present invention aims to reduce the risk caused by an overtaking vehicle or a vehicle traveling in the opposite direction entering into a vehicle making a left or right turn or a vehicle changing lanes (especially for lane changing at low speeds). vehicle) and the occurrence of vehicle collisions. The present invention solves this problem by applying automatic braking action to vehicles that are turning or changing lanes when a collision with an overtaking vehicle is imminent.

[0016] Such as figure 1 The described brake assist system for automatic braking of a vehicle A includes a monitoring device 1 . The monitoring device 1 is configured to monitor the adjacent lanes of the road, primarily, the adjacent lanes behind and beside the vehicle A, and secondarily, the adjacent lanes in front of the vehicle, thereby detecting the adjacent lanes The relative approach of road user B to the vehicle, and detection of road users traveli...

Abstract

A method for automatic braking of a vehicle (A) in order to avoid collision with road users (B) in adjacent lanes comprises monitoring adjacent lanes of a road for detecting the relative approach of road users in said adjacent lanes to said vehicle, and providing a signal indicative thereof, detecting a left or right hand turn of the vehicle and providing a signal indicative thereof, calculating, in response to said signals, if a collision with an approaching road user is imminent, and providing a signal indicative thereof, and activating, in response to the signal that a collision with the approaching road user is imminent, the brakes of the vehicle such that the vehicle can pass behind said road user, the vehicle is brought to a complete stop to avoid a collision or the collision is mitigated. The method is thereby efficient and reliable. A simple brake assist system used at this method comprises a monitoring means (1), a detecting means (4), a calculating means (2) and a control means (6) for performing said steps.

Description

technical field [0001] The invention relates to a method of assisting a driver of a vehicle by automatically braking the vehicle to avoid a collision with a road user in an adjacent lane. The invention also relates to a brake assist system for use during the method. Background technique [0002] Collisions at intersections are common in urban traffic and often result in serious injuries and / or high repair costs. A common type of intersection is the Left Turn Access / Same Direction (LTAP / SD) situation, where a vehicle is making a left or right turn while being overtaken by other road users in the adjacent lane. Said road users may be, for example, bicycles, motorcycles, motorcycles, cars or trucks. [0003] Various systems have been proposed for assisting the driver in avoiding collisions with road users in adjacent lanes. Offered solutions include systems for informing / warning the driver or systems for steering the vehicle back into its original lane, either by applying to...
