Vehicle control apparatus
First Claim
1. A vehicle control apparatus comprising:
- (a) a first speed self-adjustment control system configured to control a speed of a host vehicle based on a first command value, in a manner so as to maintain a distance of the host vehicle from a preceding vehicle or to maintain a set speed;
(b) a second speed self-adjustment control system configured to control the speed of the host vehicle by application of a longitudinal acceleration/deceleration to the host vehicle, based on a second command value determined based on a time rate of change in a lateral acceleration acting on the host vehicle when the host vehicle is rounding a curve;
(c) a deceleration selector configured to select either one of the first command value and the second command value, which selected command value is a deceleration command value so as to produce a greater deceleration exerted on the host vehicle;
(d) an acceleration selector configured to select either one of the first command value and the second command value, which selected command value is an acceleration command value so as to produce a smaller acceleration exerted on the host vehicle; and
(e) a control unit configured to control the speed of the host vehicle by driving an actuator based on the selected command value.

Abstract
In a vehicle control apparatus employing a first speed self-adjustment control system configured to control a speed of a host vehicle based on a first command value, in a manner so as to maintain a distance of the host vehicle from a preceding vehicle or to maintain a set speed, a second speed self-adjustment control system is provided for controlling the host vehicle'"'"'s speed based on a second command value determined based on information about a lateral acceleration acting on the host vehicle. Also provided is a deceleration selector configured to select either one of the first and second command values, which selected command value produces a greater deceleration exerted on the host vehicle. A control unit is configured to control the host vehicle'"'"'s speed by driving an actuator based on the selected command value.
