    摘要: In the present invention, when the wheel speeds of drive wheels are reduced by an engine brake, there are executed drive wheel control for adjusting the braking forces applied to the drive wheels by the engine brake, and driven wheel control for reducing the wheel speeds of driven wheels by an brake actuator. Drive wheel control raises lateral resistant force of the drive wheels by increasing an engine output torque, and driven wheel control brakes the driven wheels by the brake actuator such as a hydraulic brake. As a result, sufficient deceleration of a vehicle can be obtained while retaining the stability of the vehicle.

    摘要: Self-suction pumps are driven to take in brake fluid from a master-cylinder side before performing brake TRC control when at a low temperature and moreover when a vehicle is stopped. During driving of these self-suction pumps, pressure-increasing control valves and pressure-reducing control valves are both opened and brake fluid is accumulated in reservoirs. Because of this, an amount of pump discharge employed in brake TRC control when at a low temperature is assured, and responsiveness of brake TRC control is enhanced.

    摘要: Temperature of brake fluid is estimated, and a pressure-increase gradient change ratio Pup, a pressure-reduction gradient change ratio Pdw, and pump-discharge gradient change quantity Ppmp in correspondence with an amount of decline in pump-discharge capacity at the estimated brake-fluid temperature are calculated respectively. These compensation multipliers Pup, Pdw, and Ppmp are variables for obtaining a pressure-increase gradient change ratio, pressure-reduction gradient change ratio, and pump-discharge gradient change quantity identical to a time of normal temperature (i.e., a time of normal temperature when pump-discharge capacity has not declined). Accordingly, a pressure-increase time Tup and pressure-reduction time Tdw in ABS control and TRC control are calculated utilizing these compensation multipliers to obtain control performance of brake-fluid pressure similar to a time of normal temperature.

    摘要: In an apparatus for supporting drive of a mobile object, a curl component calculator projects relative motion of a environmental field in a coordinate system formed by modeling a retina sphere of a driver of the mobile object. The curl component calculator calculates each of rotational components of the projected relative motion of the environmental field around a corresponding driver's eye direction to the gaze point. A target trajectory setter sets, as a target trajectory of the mobile object, an equal-magnitude line connecting a part of the rotational components of the projected relative motion of the environmental field, the part of the rotational components having a same magnitude.

    摘要: A vehicle control system estimates the vibration states of tires by using a vehicle vibration model that is separated into a vehicle body vibration model, a chassis vibration model, and a tire vibration model with high precision. The tire vibration model in the vehicle vibration model is formed of a rear wheel tire vibration model, a front wheel tire vibration model, and a virtual coupling element vibration model that virtually couples the rear wheel tire vibration model and the front wheel tire vibration model. Influence of the vibration state that is conducted between the front wheel tires and the rear wheel tires is considered while the tire vibration model and the chassis vibration model are separated from each other, thereby making it possible to estimate the vibrations that occur in the front wheel tires and the rear wheel tires.

    摘要: A method and an apparatus for estimating behaviors of a vehicle are provided. At least two GPS antennas are located along a longitudinal axis of a vehicle so that speed vectors at the positions where the GPS antennas are located can be determined based on GPS signals received by the GPS antennas. The speed vectors are known to be estimated with high accuracy based on the GPS signals. The positions of the GPS antennas on the local coordinate system are estimated based on such highly accurate speed vectors, so that the estimated positions may also have high accuracy. Based on a line connecting these highly accurate positions of the GPS antennas, an inclination of the longitudinal axis of the vehicle is estimated. Use of the high-accuracy speed vectors enables high-accuracy estimation on the positions of the GPS antennas and the vehicle direction on the local coordinate system.
