Problems solved by technology

However, it is usually not possible to implement in practical situations, because the braking system of the vehicle may be provided by different suppliers
Therefore, in the emergency auxiliary braking solution until now, the optimal preparation time point of the braking system can only be roughly determined, which may lead to the loss of braking distance or hasty intervention braking

Embodiment Construction

[0025]The structural example set forth below is a preferred structural example of the present invention. In this structural example, the components of this structural form demonstrate each independent feature of the present invention, each of which is also a mutually independent improvement of the present invention, thus serving as the present invention alone or in other unshown combinations. Components. Furthermore, the described constructions are also limited by other or already stated features of the invention.

[0026] Functionally identical elements in the figures are provided with the same reference symbols.

[0027] figure 1 Represents a vehicle, here in particular a car or a truck. The vehicle 1 has wheels 2 on which a braking torque is generated by a brake system 3 in order to reduce the travel speed V of the vehicle 1 . Brake system 3 can have wheel brakes 4 here. Furthermore, brake system 3 has, for example, a control unit 5 with a brake controller ECU and an e...

Abstract

A method for controlling self-braking of a motor vehicle wherein a collision detection device predicts an imminent collision and determines for the self-braking a TTB braking time at which the self-braking is to start, and a brake system is operated in a standby state in which the brake system reacts to a braking request of the collision detection device with activation of wheel brakes of the motor vehicle, wherein the brake system requires a dead travel time to generate for the first time a braking torque by the wheel brakes starting from the standby state, for the self-braking. The method provides that a time period value of the dead travel time is made available in the motor vehicle, and the wheel brakes are activated at a starting time when the imminent collision is detected.

Description

technical field [0001] The present invention relates to a control device and method for controlling automatic braking of a vehicle. Automatic braking can be triggered in the usual way by a collision detection device which anticipates a possible collision of the vehicle and thus requires the braking system of the vehicle to actuate the wheel brakes. The invention also includes a vehicle having a control device according to the invention. Background technique [0002] Emergency auxiliary braking can be realized by means of the method according to the invention. When the driver of the vehicle does not perceive the objects around the vehicle or even if he does, the applied braking force is not enough, emergency auxiliary braking requires the braking system to generate a large deceleration (negative acceleration) for emergency braking or automatic braking. But every braking system has a reaction time before it starts to produce vehicle deceleration. In order to reduce the reac...
