A driving assistance apparatus measures a position and a movement direction of a target object present in the periphery of an own vehicle. The driving assistance apparatus performs a driving assistance process of the own vehicle when the measured position of the target object is within a determination area provided in the periphery of the own vehicle. The driving assistance apparatus corrects the determination area in a direction at which the target object is measured, when the target object is determined to be moving towards the determination area based on the measured movement direction of the target object.

A collision determination device is mounted to an own vehicle and determines a probability of a collision with a moving object. The collision determination device determines whether or not an own vehicle will collide with a moving object that is detected within a captured image. The collision determination device determines whether or not the moving object is in a shielded state where at least a portion of the moving object is hidden behind another object or the moving object appears from behind another object. The collision determination device sets an amount of time required for the collision determining means to complete a determination related to the collision to a shorter amount of time when the moving object is in the shielded state, compared to when the moving object is not in the shielded state.

Collision determination device and collision mitigation device

A driving support system detects a target area ahead of the vehicle, a position or a moving direction, etc. of an object such as a pedestrian or another vehicle by using a camera or radar, as well as determines a probability of collision between the own vehicle and the object based on the position, etc. of the object, and performs a driving support for avoiding the collision when the probability of the collision is high. Further, a sensitivity of determination is set high when the object remains in the target area, or when the object is moving towards the target area, while the sensitivity is set low when the object is not present in the target area, or the object is moving away from the target area.

In a vehicle control system performing collision avoiding control when a collision with a preceding vehicle cannot be avoided by normal running condition control, driving safety is improved by prompting a driver to intervene in the vehicle's control in a reliable manner. When a set switch is turned on in the 'cancel' state, the transition to the 'in-control, inter-vehicle distance control' sub-state occurs and an inter-vehicle distance control is performed. If a collision with a preceding vehicle cannot be avoided by the inter-vehicle distance control (if the collision alarm flag XA=1), transition to the &#x201c;in-control, collision alarm&#x201d; sub-state occurs and a collision alarm is generated. If the acceleration required for avoiding collision is further increased (if the collision avoiding control flag XC=1), the state transits to the &#x201c;in-control, collision avoiding control&#x201d; sub-state, and a collision avoiding control is performed.

Vehicle control system

The present invention provides inspection of a transmission with higher precision and in a shorter period of time. Before a finished A/T is inspected, a V/B ASSY and an ECU are inspected together by a V/B tester in a subsidiary line. A solenoid current command value (a characteristic value inherent in the A/T) for a linear solenoid of the V/B ASSY is corrected and written into the ECU through CAN communication. Spring load of a return spring SP and stroke of the piston of a hydraulic servo for a frictional engagement element are measured. Actually measured values or corrected values of the spring load and the stroke are stored. In the final inspection of the A/T a finished-product tester reads the stored characteristic values and transmits them to the ECU integrated with the A/T through CAN communication. The characteristic values are then written into the ECU. The finished-product tester inspects the finished A/T product, using the characteristic values thus written into the ECU.

In a vehicle speed control system, each node existing ahead of a vehicle is detected, and a stable running speed at which the vehicle runs stably when the vehicle passes over each node, and a deceleration needed to accelerate/decelerate the vehicle so that the vehicle speed becomes the stable running speed at each node by the time when the vehicle arrives at the node are successively calculated. On the basis of the deceleration at each node, a point at which the maximum deceleration value is achieved is selected, and the vehicle is subjected to deceleration control so that the vehicle speed becomes the stable running speed at the point. When a point at which the curve degree is maximum is different from a point at which the deceleration value is maximum and also the point is located ahead of the vehicle, further necessary deceleration control is carried out.

Vehicle speed control system and program

A cruise control apparatus can control a host vehicle to run with a fixed separation from a preceding vehicle when such a preceding vehicle is detected based on received radar signals and to run at a preset fixed speed when no preceding vehicle is detected. The cruise control apparatus is configured to respond to one of a set of predetermined actions by the vehicle driver, which indicate an intention to change the vehicle speed, by making it easier or more difficult for a preceding vehicle to be detected, in accordance with whether the indicated intention may signify that an actual preceding vehicle is not being detected or may signify that a non-existent preceding vehicle is being detected and that the host vehicle speed has been reduced accordingly. Improved performance is thereby achieved by utilizing the cognitive abilities of the driver to augment the detection operation of the cruise control apparatus.

Recognition result of an objective recognized as a preceding vehicle is analyzed to judge whether this objective is correctly detected as a vehicle or not. A relative acceleration is calculated based on a relative speed corresponding to the objective when analysis result shows properness of this objective as a vehicle. The relative acceleration is set to 0 when analysis result shows improperness of the objective. An inter-vehicle control amount is corrected based on the obtained relative acceleration. The distance between the preceding vehicle and the controlled vehicle is controlled based on the corrected inter-vehicle control amount.

A collision avoidance control system for a vehicle is provided which is designed to determine a target collision avoidance deceleration required for a system vehicle equipped with this system to bring a relative speed between the system vehicle and a target object into agreement with substantially zero without a physical collision with the target object and to determine a possibility of collision with the target object as a function of the target collision avoidance deceleration. When the possibility of collision is higher than a given threshold level, the system starts to decelerate the system vehicle. This enables the avoidance of collision with the target object at a decreased operation load on the system.
