A system for assisting an operator in driving a vehicle. The system calculates risk potential associated with the vehicle. Responsive to an acceleration command issued by the operator via an operator-controlled input device to perform an intended acceleration operation, the system conveys information related to the calculated risk potential by modifying a relationship of an amount of acceleration corresponding to an operation amount of the operator-controlled input device, based on the calculated risk potential.

Driving assisting system, method and vehicle incorporating the system

A vehicle driving assist system has a controller configured to calculate a risk potential indicative of the degree of convergence between a host vehicle in which the system is installed and a preceding obstacle. Then, the controller performs a driver notification controlling operation that produces a driver notification stimulus based on the risk potential. Considering the acceleration of the preceding obstacle, the speed of the host vehicle, and the following distance between the host vehicle and the preceding obstacle, the controller calculates a threshold value for determining when to commence the control of the driver notification controlling operation.

Vehicle driving assist system

A motor vehicle includes a vehicle driving operation support system. The vehicle driving operation support system senses an environment surrounding the motor vehicle; senses a traveling condition of the motor vehicle; calculates a risk potential of the motor vehicle on a basis of the sensed environment and the sensed traveling condition; controls the motor vehicle on a basis of a control setpoint. The vehicle driving operation support system sets on a basis of the calculated risk potential the control setpoint to a provisional setpoint effective for reducing the risk potential; senses driver's operation in reaction to the controlling operation with the control setpoint set to the provisional setpoint; and sets the control setpoint to a normal setpoint on a basis of the sensed driver's operation.

Vehicle driving operation support apparatus/method and vehicle

A method and system for assisting a driver operating a vehicle traveling on a road includes determining an obstacle as a target obstacle in the path of the vehicle and providing information on the target obstacle, regulating at least one of a reaction force input (F) to the driver, a driving force applied to the vehicle and a braking force applied to the vehicle in response to a control amount determined; measuring a width of the target obstacle; and correcting the control amount based on the measured width (w).

Method and vehicle reacting to the detection of an in-path obstacle

A vehicle driving assist system executes an actuation reaction force control of accelerator pedal, a driving force control or a braking force control in a manner that is appropriate in consideration of the traffic situation in which the vehicle is being driven. The vehicle driving assist system calculates a risk potential that indicates the degree of convergence between the vehicle and an obstacle existing in front of the vehicle based on a prescribed control pattern. Then, based on the risk potential, the accelerator pedal actuation reaction, the host vehicle driving force and/or the host vehicle braking force are controlled. The intent of the driver regarding acceleration and deceleration based on the actuation state of the accelerator pedal is preferably used in controlling one or all of the accelerator pedal actuation reaction, the host vehicle driving force and the host vehicle braking force.

A lane deviation avoidance system is arranged to execute a lane deviation avoidance control of controlling a vehicle behavior of the host vehicle so as to avoid the host vehicle from deviating from a traveling lane when the lane deviation tendency is detected, to suppress the driving force when the lane deviation tendency is detected, and to set a controlled variable of the lane deviation avoidance control according to a degree of the suppression of the driving force.

Intelligent driving assistance method and system

In a vehicle dynamics control apparatus capable of balancing a vehicle dynamics stability control system and a lane deviation prevention control system, a cooperative control section is provided to make a cooperative control between lane deviation prevention control (LDP) and vehicle dynamics stability control (VDC). When a direction of yawing motion created by LDP control is opposite to a direction of yawing motion created by VDC control, the cooperative control section puts a higher priority on VDC control rather than LDP control. Conversely when the direction of yawing motion created by LDP control is identical to the direction of yawing motion created by VDC control, a higher one of the LDP desired yaw moment and the VDC desired yaw moment is selected as a final desired yaw moment, to prevent over-control, while keeping the effects obtained by both of VDC control and LDP control.

The system comprises a lane detecting device, a running condition detecting device, a deviation judging device, and a vehicle behavior control device. The vehicle behavior control device controls a behavior of the vehicle so as to generate a yaw moment in the direction to prevent the vehicle from deviating from the running lane. The lane detecting device detects the running lane based on a variation in a running direction of the vehicle due to the yaw moment generated by the vehicle behavior control device. A method for preventing lane deviation of a vehicle is also provided.
