Abstract:
A slip control apparatus includes a driving torque calculating means calculating driving torque, a driving torque applying means applying the calculated driving torque to driving wheels, and a slip restraining means restraining slippage at each driving wheel when the slippage occurs at each driving wheel, wherein when the slippage occurs at each driving wheel, the driving torque calculating means calculates demanded torque and adds consumed driving torque, which corresponds to the driving torque consumed for restraining the slippage at each driving wheel by the slip restraining means, to the calculated demanded torque to calculate the driving torque.
Abstract:
A system for controlling a vehicle that controls driving force and braking force such that a vehicle speed is maintained at a target vehicle speed. More specifically, when the vehicle speed exceeds the target vehicle speed, the system for controlling a vehicle maintains the driving force at or above a predetermined value, and applies braking force to the vehicle such that the vehicle speed is maintained at the target vehicle speed. This provides the vehicle with sufficient driving force for uphill driving following the downhill driving, and thus to travel uphill without significant speed loss. In other words, the vehicle ascends the uphill road smoothly at an approximately constant speed.
Abstract:
A vehicle running control apparatus, which performs automatic running control by controlling an engine for applying a driving torque to a vehicle C and a brake device for applying a braking torque to the vehicle C such that a vehicle speed of the vehicle C becomes equal to a preset target vehicle speed, determines, on the basis of a target driving torque ETo calculated to apply the driving torque to the vehicle C and a target braking torque BTo calculated to apply the braking torque to the vehicle C, whether or not the vehicle C is running on a road difficult to run on, when automatic running control is performed. When it is determined that the vehicle C is running on the road difficult to run on, automatic running control is terminated.
Abstract:
A running control apparatus for a vehicle includes a required driving output deciding unit that decides a required driving force of a driving system of the vehicle on the basis of an integrated value of a difference between a target vehicle speed and an actual vehicle speed, a driving control unit that controls the actuation of the driving system on the basis of the required driving force, and a determination unit that determines whether or not the required driving force is unrealizable in the control of the driving system due to the intervention of additional control. The required driving output deciding unit imposes a limit on an increase or a decrease in the required driving force when the determination unit determines that the required driving force is unrealizable in the control of the driving system.
