摘要： When a vehicle stops, a brake control unit maintains a braking force applied on a wheel by a braking-force application unit for maintaining a halted state. In this state, if a driver depresses the accelerator pedal to execute starting of the vehicle, the braking force is gradually decreased, and the vehicle starts at a speed that accords with a degree of accelerator opening and a gradient of a road on which the vehicle is stopped. When a movement direction at this time is the same as a movement direction intended by the driver, the braking force is decreased to zero for smooth starting. When the movement direction is opposite to the intended movement direction, the braking force is increased to control the movement in the opposite direction, such that the movement changes from the opposite direction to the same direction, and finally, smooth starting in the desired direction is executed.

摘要： A grip factor estimating apparatus includes a steering torque detecting unit M1, and an assist torque detecting unit M2. When a self-aligning torque estimating unit M6 estimates self-aligning torque generated in front wheels on the basis of detection result of the detecting unit, the quantity of influence of longitudinal force on self-aligning torque is removed on the basis of longitudinal force acting on the front wheels and estimated by a longitudinal force estimating unit M15 and a front wheel slip angle estimated by a front wheel slip angle estimating unit M9y. A grip factor estimating unit M12 estimates the grip factor of the front wheels on the basis of change in self-aligning torque in accordance with the side force.

摘要： A first ECU 30 detects a steering torque applied to a steering system, estimates a self-aligning torque generated in a front wheel on the basis of the steering torque, and estimates a side force for the front wheel on the basis of lateral acceleration and a yaw rate. The first ECU 30 estimates a grip factor ε for the front wheel on the basis of a change of the self-aligning torque to the side force. The first ECU 30 judges whether the grip factor is below a second OS (oversteer) start threshold value. A second ECU 40 controls the transfer ratio according to the vehicle state when the grip factor is less than the second OS start threshold value.

摘要： An internal planetary gear mechanism reduces a load applied to tooth surfaces of an external gear and an internal gear, a sliding portion such as a bearing and the like. By setting the amount of eccentricity α of an eccentric part to be larger than a theoretical value, a distance between the center of the external gear and the center of the internal gear is increased to allow the reduction of a loss in the bearing and on the tooth surfaces of the gears, and a mesh zone between the internal gear and the external gear can be reduced to decrease a part at a large pressure angle, thereby reducing a loss generated by a large pressure angle. As a result of reduction in the mesh zone between the external gear and the internal gear, rolling contact of the gears is maintained.

摘要： The vehicle operation control apparatus multiplies the variable gain G controlled based on the vehicle velocity V, the steering angle &thgr;h, the steering angle velocity &ohgr;h and the actual steering angle &thgr;T with the steering angle &thgr;h, and controls the actual steering angle &thgr;T of the driven wheels on a result of this multiplication. Consequently, the additional turning time gear ratio Ga1 or the turning-back gear ratio Ga2, set up individually, can be selected depending on the turning direction of the steering wheel. Therefore, the steering feeling both at the time of additional turning and turning-back can be improved.

摘要： A fuel injection control apparatus includes a booster apparatus, in which a cylinder chamber is divided into first and second fluid chambers by a piston. The operative area of the piston facing the first fluid chamber is sufficiently greater than that facing the second fluid chamber. Pressurized fuel is supplied to the first fluid chamber through a first check valve. The fluid is delivered from a second fluid chamber to a fuel injection valve via a second check valve. A fluid passage is formed between the first and second fluid chambers. A third check valve is set in the fluid passage, whereby the fuel is allowed to flow only from the first fluid chamber toward the second fluid chamber. The booster piston is located by means of a first piezoelectric device which includes a plurality of piezoelectric elements stacked in layers. When high voltage is applied to the first piezoelectric device to extend it, the piston is moved toward the first fluid chamber. High-voltage power from a second piezoelectric device, which faces the inside of an engine cylinder, is supplied to the first piezoelectric device via a backflow-preventing element. The first piezoelectric device is controlled for discharge in response to the injecting timing.
