Embodiment Construction

[0089] (constitute)

[0090] figure 1 A schematic configuration of a vehicle equipped with a motion control device (hereinafter referred to as the present device) according to an embodiment of the present invention is shown. This device includes an engine EG as a power source of the vehicle, an automatic transmission TM, a brake actuator BRK, an electronic control unit ECU, and a navigation device NAV.

[0091] Engine EG is, for example, an internal combustion engine. That is, the opening degree of the throttle valve TV is adjusted by the throttle actuator TH in accordance with the driver's operation of the accelerator pedal (accelerator operating member) AP. Fuel is injected from a fuel injection actuator FI (injector) in proportion to the amount of intake air adjusted according to the opening degree of the throttle valve TV. Accordingly, an output torque corresponding to the driver's operation of the accelerator pedal AP can be obtained.

[0092] The automatic transmiss...

Abstract

The present invention provides a motion control device for a vehicle for implementing suitable speed reduction control when traveling through a curve existing ahead of the vehicle. In the device, the speed of the vehicle, the curve shape existing ahead of the vehicle on a road on which the vehicle is traveling, and a relative position of the vehicle to the curve are obtained. Based upon the shape of the curve, an appropriate vehicle speed of the vehicle to travel through the curve is determined. Then a speed reduction control on the vehicle based on the appropriate vehicle speed is determined.

Description

technical field [0001] The invention relates to motion control devices for vehicles. Background technique [0002] Conventionally, there is a device described in Patent Document 1 as one of such devices. In the device described in Patent Document 1, the deceleration distance required to decelerate when entering a curve and the remaining distance from the current position of the vehicle to the start point of the curve are obtained so that the vehicle speed becomes an appropriate entry speed when the vehicle enters a curve. Then, when the gradually decreasing remaining distance reaches the deceleration distance, the deceleration control is started, and when the remaining distance becomes 0 and the vehicle passes the curve start point, the deceleration control is terminated. [0003] In addition, as one of such devices, there is a device described in Patent Document 2. In the device described in Patent Document 2, since the deceleration control is performed when traveling on ...
