A drive source controller is configured to control a drive torque of a drive source that drives a vehicle. The drive source controller is configured to prohibit acceptance of drive source required torque from a cruise controller when automatic braking control is activated during cruise control, or not output the drive source required torque to the drive source controller when the automatic braking control is activated during the cruise control.

Vehicle control method and vehicle control device

The present invention provides a vehicle control method capable of suppressing an increase in the frequency of stopping and restarting of the engine when the braking device is activated at the self-driving mode. When the operation mode is set as self-driving, the braking device is activated in accordance with a system deceleration request to keep an actual vehicle-speed at a target vehicle-speed or change the actual vehicle-speed at the target vehicle-speed or lower depending on environment surrounding the vehicle. Further, a braking amount is estimated, the braking amount is a magnitude of a braking force generated from the activated braking device. When the braking amount is an engine-stopping enabling threshold or more, enabling stopping is allowed. When the braking amount is less than the engine-stopping enabling threshold, enabling stopping is not allowed.

Provided is a control method for hybrid vehicles that change an operation mode of the vehicle between HEV mode and EV mode in accordance with the size of a target drive force. When the manual-driving mode is set, the target driving force is calculated based on a vehicle-speed and a driver's driving operation, and when self-driving is set, the target driving force is calculated based on a target vehicle-speed and an actual vehicle-speed. When self-driving is set, an amount to enlarge a dead-zone width W&#x3b1; to control the motor generator to perform powering relative to the dead-zone width when the manual-driving mode is set is set larger than an amount to enlarge a dead-zone width to control the motor generator to perform regeneration relative to the dead-zone width when the manual-driving mode is set.

The acquisition unit acquires engine operating information from a plurality of vehicles, during the operation of the motor/generator. The engine operating information includes a moving distance or an engine operating time from the start of to the stop of the engine, and an engine operating position indicating the point at which the engine is operating. The area identifying unit identifies on map data an engine start-up suppressing area in which the start of the engine is suppressed based on the engine operating information.

Hybrid vehicle management system, hybrid vehicle control apparatus, and hybrid vehicle control method

A vehicle control system, a server and a vehicle control device which improve energy efficiency of a vehicle based on the information of other vehicles is provided. The system includes a first energy information acquiring mechanism that acquires energy information indicating the energy efficiency of the vehicle including at least accelerator pedal opening information, an identification mechanism that identifies the vehicle of good energy efficiency among a plurality of vehicles based on the energy information, and a drive system control mechanism that controls the drive system of the own vehicle based on the accelerator pedal opening of the other vehicle that has been identified as energy efficient.

Vehicle control system, server and vehicle control device

Provided herein is a vehicle drive force control. When a driver requests to start the vehicle with the brake OFF and depresses the accelerator pedal, a target drive torque exceeds a gradient load. To avoid excess current being supplied to the motor, the upper limit of motor speed, which is the input speed of a second clutch, is set to a value less than a slip detectable limit value at which it becomes possible to detect slip rotation, i.e. the difference over the output side rotation speed. When the target drive torque exceeds the gradient load, the lower limit of the input speed of the second clutch (the motor speed) is set to a value equal to or greater than the slip detectable limit value so that the required driving force can be achieved by the gradient load corresponding driving force control.
