When it is judged that a possible collision of the own vehicle with a preceding vehicle is avoidable by operation of either one of the brake pedal and steering wheel, a first grade braking force is automatically produced. While, when it is judged that the possible collision is unavoidable by operation of either of the brake pedal and steering wheel, a second grade braking force is automatically produced, which is greater than the first grade braking force.

Automatic brake system of motor vehicle

An automatic brake system for a vehicle is disclosed. Based on a possibility that a potential collision with an obstacle preceding the vehicle can avoided by braking, and a possibility that the potential collision can be avoided by steering, the system automatically controls a braking operation for collision-avoidance. A condition of starting the automatic braking operation and a characteristics of the operation are determined based on calculation or estimation of a condition of the path where the vehicle is traveling, such as a relative speed, widths of spaces on sides of the obstacle, and steering characteristics.

Packaging object supplying apparatus, box body supplying apparatus, boxing apparatus, packaging system and packaging method

A braking control device performs a steering and/or avoidance possibility determination based on the state of the vehicle to execute automatic vehicle braking when an obstacle in front of the vehicle cannot be avoided by steering and/or braking. The device determines that the obstacle can be avoided by steering when the correlation value between steering avoidance time and relative velocity is smaller than the distance from the vehicle to the obstacle. The steering avoidance time is set to a shorter value when the suspension characteristic is stiffer and the sideways force generated by the front wheels is larger. The steering avoidance time is set successively shorter for low, high, and medium speed travel regions, respectively, to reflect the behavior response characteristic of the vehicle with respect to steering input. The vehicle deceleration that would occur if the driver released the accelerator pedal is considered in the braking avoidance possibility determination.

Braking control device

The present invention pertains a controlling scheme for brake torque, which is applied, as a stand-by braking torque, to wheels of an automotive vehicle upon determination that operator braking action is imminent. A braking system applies brake torque in response to a brake signal The brake torque applied to the vehicle is monitored and the brake signal is modified based on the monitored brake torque to alter the brake torque.

A braking control system includes an object detector, a host vehicle speed sensor, and a control unit configured to be electronically connected to at least the object detector and the host vehicle speed sensor for automatically controlling, depending on a host vehicle speed and a relative distance, a braking force needed for an automatic braking operation, containing preliminary braking control and supplementary braking control, without driver's braking action when a host vehicle is approaching a frontally positioned object. The control unit detects the presence or absence of a driver's intention for lane-changing. In the presence of the driver's intention for lane-changing, the preliminary braking control initiated prior to the driver's braking action is inhibited or the degree of limitation on the supplementary braking control, through which a value of a controlled quantity is brought closer to a target deceleration rate needed for collision-avoidance, is reduced.

The transition braking torque may be applied using friction brakes associated with wheels, respectively. The ADR braking torque is represented by an ADR braking request that is generated when an actual distance from the preceding vehicle in front becomes less than a set desired distance. The ADR braking request may be provided at an ADR controller.

The present invention pertains a controlling scheme for build-up or variation rate at which brake pressure increases till completion of pressure build-up for stand-by brake torque. Stand-by brake torque control begins with recognition of emergency or occurrence of operator reaction or quick release of accelerator. During initial stage of the stand-by brake control, brake pressure increases till completion of pressure build-up for stand-by brake torque before vehicle operator depresses a brake pedal. Build-up or variation rate at which brake pressure increases till completion of pressure build-up for stand-by brake torque is determined in response to time left before the operator depresses the brake pedal. Period of time left before the operator depresses the brake pedal varies with differing events that have initiated the stand-by brake torque control.
