An engine ECU and a brake ECU of a vehicle control apparatus performs any one of a mechanical brake which converts a kinetic energy using rotation of a driving wheel rotation into thermal energy using friction and a regeneration brake which converts the kinetic energy of the driving wheel rotation into electric energy using regeneration, during a vehicle deceleration, after an engine brake changes a deceleration ratio which is a rotation number ratio of driving wheels with respect to the rotation number of an engine.

Vehicle engine brake control apparatus

There is provided a running support system for a vehicle, which supports running of a vehicle by using a radar and image recognition means as obstacle detecting means, and in which appropriate support control based on a result of detection performed by each control means is set. A result of obstacle detection performed by a millimeter wave radar () is checked against a result of obstacle detection performed by image recognition means (). Then, a starting condition for the running support control is changed depending on whether an obstacle has been detected by both the millimeter wave radar () and the image recognition means (), or an obstacle has been detected by only one of the millimeter wave radar () and the image recognition means (). Thus, the control support is performed based on an inattentive condition of a driver.

Running support system for vehicle

A curve-travel target acceleration calculator calculates a curve-travel target acceleration. A first curve-travel target acceleration calculator calculates a first target acceleration corresponding to a gentle curve, and a second curve-travel target acceleration calculator calculates a second target acceleration corresponding to a sharp curve. The curve-travel target acceleration is set to the smaller of the first target acceleration and the second target acceleration. A follow-up target acceleration calculator calculates a follow-up target acceleration and a constant-speed target acceleration calculator calculates a constant-speed target acceleration. An arbitrator selects as a target acceleration the minimum out of the curve-travel target acceleration, the constant-speed target acceleration, and the follow-up target acceleration.

Running control device for vehicle

An object detection system includes a radar detection means (), an image detection means (), and a collating means (). The collating means () performs a collation between an object detected by the radar detection means () in a present collation and an object that has been determined as being detected by the radar detection means () and the image detection means () in a previous collation (S, S), further performs a collation between an object detected by the image detection means () in a present collation and an object that has been determined as being detected by the radar detection means () and the image detection means () in the previous collation (S, S) when it is determined that the identical object is detected by the radar detection means () and the image detection means () in the previous collation. Then the collating means () determines whether the radar detection means () and the image detection means () detect the identical object based on the collations (S).

Object detection system and object detection method

An object detection system is provided with radar detection means (), image detection means (), and collating means (). The collating means () detects a combination of an object detected by the radar detection means () and an object selected among those detected by the image detection means (), which is the closest to the object detected by the radar detection means (S, S), detects a combination of an object detected by the image detection means () and an object selected among those detected by the radar detection means (), which is the closest to the object detected by the image detection means (S, S), and determines when there is a coincidence between the combination of the object detected by the radar detection means () and the selected object as being closest thereto and the combination of the object detected by the image detection means () and the selected object as being closest thereto, that the object detected by the radar detection means () is the same as the object detected by the image detection means (S).
