A cruise control device and an obstacle detection device are provided which achieve a safe and appropriate tracking control by avoiding a sudden recognition of a short following distance when a preceding vehicle is found in an uphill or downhill gradient, in a curve, or at an intersection, or by reducing the damage of a crash when the crash cannot be avoided. An obstacle determination process section is provided which receives information from a sensor which detects an obstacle, receives terrain information of the position of the host vehicle from a navigation device, and determines the presence of the obstacle when a predetermined condition is satisfied after the sensor detects the obstacle. The predetermined condition to determine the presence of the obstacle is changed based on the terrain information of the position of the host vehicle received from the navigation device.

Vehicle control device and vehicle control method

A vehicle speed control system includes a road shape recognition unit which recognizes a road shape, a target speed setting unit which sets a target speed according to the road shape, a speed control unit which controls the host vehicle's speed according to the target speed, a parameter detecting unit which detects at least one of parameters representing the driver's steering rotation, a yaw rate of the host vehicle, and a lateral acceleration of the host vehicle, and a first acceleration determining unit which, after the speed control unit has decelerated, determines whether or not to accelerate the host vehicle according to reference parameters based on a road shape and the host vehicle's speed and parameters detected by the parameter detecting unit, wherein if the first acceleration determining unit has determined to accelerate, the target speed setting unit sets a target speed of the host vehicle according to a predetermined acceleration.

Vehicle speed control system

A collision between a vehicle and an obstacle is estimated, and based on the estimation result, vehicle deceleration control is performed by a brake actuator to reduce the collision and vehicle wheel load is controlled by a suspension actuator.

Vehicle safety control apparatus for avoiding collision

A vehicle control system includes a route setting unit for setting a route from a start point to a destination; an information obtaining unit for obtaining from a memory position information of at least one base point and at least one control point existing in the route set by the setting unit; a base point recognition unit for recognizing that a current position of a vehicle reaches a position of the base point obtained by the obtaining unit; a running situation monitoring unit for determining as a predetermined distance a running distance from the base point most lately recognized by the recognition unit; and a control unit for executing an advanced control to the vehicle if the predetermined distance obtained by the monitoring unit is shorter than any of first and second threshold distances, when the current position reaches a position of the control point obtained by the obtaining unit.

Vehicle control system, vehicle control method, and vehicle control program

On the basis of headway distance information issued from a headway distance detecting device for detecting a headway distance between a controlled vehicle and a preceding vehicle and terrain shape information issued from a terrain shape estimating device for estimating a terrain shape around the position of the controlled vehicle, a terrain shape at a position spaced from the position of the controlled vehicle by the headway distance is detected, and the speed of the controlled vehicle is controlled according to the terrain shape information.

Adaptive cruise control system and navigation system's media with vehicle control information included
