摘要:
Before the termination of the fuel-cut control, the vehicle control system reduces a pumping loss by increasing an air intake and a load torque of an auxiliary device thereby preventing the vehicle to be decelerated excessively, and after the termination of the fuel-cut control, the vehicle control system increases the load torque of the auxiliary device thereby preventing the vehicle to be accelerated abruptly. Therefore, the vehicle speed will not be lowered unnecessarily before the termination of the fuel-cut control so that an execution time of the fuel-cut control can be extended. Moreover, driving comfort can be improved by thus reducing a change in acceleration.

A parking assistance apparatus includes a display unit that displays an image of a scene behind a host vehicle. At least when the host vehicle moves forward or when the host vehicle is stopped, the display unit displays an indication including a plurality of kinds of trajectories along which the host vehicle is able to back up from a point at which the host vehicle is currently positioned, in a manner such that the indication is superimposed on the image of the scene behind the host vehicle.

In deviation prevention support ECU 10 in driving operation support system 1, an applied torque by steering torque applier 17 is set based on a vehicle speed of a vehicle. The applied torque is set to increase with increase of the vehicle speed. An upper limit according to the vehicle speed is set for this applied torque. Furthermore, in a Start interval in application of the applied torque, a rate of increasing to reach a maximum is determined according to the maximum of the applied torque. In a close interval, the applied torque is decreased at a rate different from that in the Start interval, and the absolute rate of increasing the torque in the Start interval is set to be larger than the absolute rate of decreasing the torque in the close interval.

A driving control apparatus of the present invention has a driving road keeping device for providing a torque to a steering mechanism so as to keep a vehicle traveling at a predetermined position on a driving road; a driving road departure warning device for issuing a warning of a departure from the driving road on the basis of a position of the vehicle relative to the driving road; and a setting device for setting a need or no need for execution of a control of the driving road keeping device or the driving road departure warning device. Where the setting device sets a need for execution of the control, the control of the driving road keeping device is executed when an activation condition of the driving road keeping device is met and when a cruise control device is active. Where the setting device sets a need for execution of the control, the control of the driving road departure warning device is executed when the activation condition of the driving road keeping device is not met or when the cruise control device is inactive. According to the present invention, a lane departure warning function and a lane-keep assist function are selectively executed in conjunction with activation/deactivation of the cruise control device and the activation condition of the driving road keeping device, whereby, even with an automatic stop of operation of either one of the functions, the other function can prevent the vehicle from departing from the lane.

In a brake system of a hybrid type vehicle equipped with a front regeneration brake workable at a first regeneration efficiency, a rear regeneration brake workable at a second regeneration efficiency different from the first regeneration efficiency, a front friction brake, a rear friction brake and a control device for operating the front and rear regeneration brakes and the front and rear friction brakes, when the vehicle is braked at a controlled braking force, either of the front and rear regeneration brake workable at a higher regeneration efficiency than the other applies as much a braking force to the corresponding front or rear wheels as available thereby under a condition that a ratio of a braking force applied to the rear wheels to a braking force applied to the front wheels is not larger than a value predetermined therefor, with a remainder of the controlled braking force, if any, being applied by at least one of the other of the front and rear regeneration brakes and the front and rear friction brakes.

Characteristic lines A to D of lateral acceleration G-required torque T in determination of required torque T are used as switched according to increase/decrease of the absolute value of the lateral acceleration, and the direction thereof. The lines A, C used in increase of the absolute value of the lateral acceleration G are so set that the absolute value of required torque T becomes larger at the same lateral acceleration G (G≠0) than that with the lines B, D used in decrease of the absolute value of the lateral acceleration G. The difference between line A and line B (the difference between line C and line D as well) at the same lateral acceleration G is so set that the difference near the lateral acceleration of 0 is smaller than that in the other regions. Particularly, it is preferable to set the required torque T to 0 at the lateral acceleration G of 0.
摘要:
A driving support system according to the present invention is provided with an actuator for steering steered wheels and performs a driving support control of a vehicle to apply an additional torque to a steering mechanism incorporating the steered wheels, by means of the actuator to steer the steered wheels. The driving support system has an image taking device for taking a forward image ahead the vehicle, a controller for driving the actuator to generate the torque on the steering mechanism on the basis of the forward image acquired by the image taking device, to perform the driving support control, a steering wheel torque detector for detecting a steering wheel torque on a steering wheel, and a control suppressor for prioritizing a steering operation by a driver to the driving support control when a magnitude of the steering wheel torque is not less than a predetermined value. The control suppressor sets the predetermined value so that the predetermined value in a case where a direction of the steering torque for the driving support control agrees with a direction of the steering wheel torque by the driver is larger than the predetermined value in a case where the direction of the steering torque does not agree with the direction of the steering wheel torque. This configuration enables the system to accurately grasp a driver's intension and to prioritize the steering operation by the driver more accurately when the steering operation by the driver should be prioritized to the driving support control.
