Automatic braking is a technology for automobiles to sense an imminent collision with another vehicle, person or obstacle; or a danger such as a high brakes or by applying the brakes to slow the vehicle without any driver input. Sensors to detect other vehicles or obstacles can include radar, video, infrared, ultrasonic or other technologies. GPS sensors can detect fixed dangers such as approaching stop signs through a location database.
Collision avoidance with active steering and braking
A method for collision avoidance using automated braking and steering comprising: determining an actual distance to an obstacle in a path of a vehicle; determining a relative velocity between the obstacle and the vehicle; determining a first distance sufficient to avoid collision by braking only; determining a second distance sufficient to avoid collision by combined braking and steering around the obstacle. The method also includes: applying braking if at least one of, the first distance exceeds the actual distance and the first distance is within a selected threshold of the actual distance. If the actual distance exceeds the second distance and a lane change is permitted, steering control to affect a lane change is applied.

A method and system are disclosed for tracking objects which are crossing behind a host vehicle. Target data from a vision system and two radar sensors are provided to an object detection fusion system. Salient points on the target object are identified and tracked using the vision system data. The salient vision points are associated with corresponding radar points, where the radar points provide Doppler radial velocity data. A fusion calculation is performed on the salient vision points and the radar points, yielding an accurate estimate of the velocity of the target object, including its lateral component which is difficult to obtain using radar points only or traditional vision system methods. The position and velocity of the target object are used to trigger warnings or automatic braking in a Rear Cross Traffic Avoidance (RCTA) system.

Automotive collision mitigation apparatus

A collision mitigation controller drives a target brake to be controlled for assisting driver's collision-avoidance operation when a calculated collision time is less than an automatic brake a1 judgment line which is determined in advance. The controller drives the automatic brake a1 in order to mitigate damage generated by a collision with an obstacle or another vehicle when the collision time is less than an automatic brake a2 judgment line which is also less than the automatic brake a1 judgment line. The controller decreases the braking force for the automatic brake a2 when judged that the automatic brake a1 is not driven, as compared with the judgment where the automatic brake a1 is driven. When the automatic brake a2 drives the target brake, it is possible to avoid a collision where own vehicle is struck from behind by the rear vehicle which runs on a same traffic lane.

In a vehicle control system, when an inter-vehicular distance between a subject vehicle and a preceding vehicle detected by a radar device is less than or equal to a predetermined value, automatic braking is performed or an alarm is activated to alert a driver to prevent a collision. A stationary object detection threshold value of a reception level of a reflected wave for detecting a stationary object is set higher in a predetermined region compared to a moving object detection threshold value of a reception level of a reflected wave emitted from the radar device for detecting a moving object such as a preceding vehicle. Thus, the system prevents a gate or an article in the roadway, which are not obstacles, from being erroneously recognized as obstacles. As such, unnecessary automatic braking and alarm activation for the gate and the article in the roadway can be prevented.

Device for motor vehicles designed to prevent traffic accidents or to reduce their injurious consequences. The extent of injuries in traffic accidents can be reduced significantly by employing the vehicle bumper (1) as a crumple (deformation) zone. A sensor (2) is used to record this distance from and speed relative to an obstacle in the direction of travel.

The device can also be provided with a system to warn of dangerous traffic situations, and to brake the vehicle automatically or reduce its speed if the risk of a collision exists. In the case of trucks and buses, the bumper (1) may be deployed by means of a pneumatic cylinder (4) and valve (7), which are controlled by the vehicle's ordinary speedometer.
