摘要： An electrically driven vehicle includes a motor configured to supply the vehicle with a braking force or a driving force corresponding to an accelerator operation amount. The braking force is controlled when the accelerator operation amount is less than a predetermined value and the driving force is controlled when the accelerator operation amount is the predetermined value or more. A torque target value at which the motor is caused to output a braking or driving torque corresponding to the accelerator operation amount is calculated. A disturbance torque acting on the motor as a resistance corresponding to a road surface gradient is estimated, and a correction to remove the disturbance torque from the torque target value is performed. The correction amount is reduced in a downhill road when the accelerator operation amount is less than the predetermined value and a vehicle speed is larger than a predetermined vehicle speed.

摘要： When a driver demand torque is not greater than a target braking/driving torque, the acceleration/deceleration of the vehicle is controlled depending on the target braking/driving torque, when the driver demand torque exceeds the target braking/driving torque, the acceleration/deceleration is controlled depending on the driver demand torque, when the accelerator pedal operation amount decreases after the driver demand torque exceeds the target braking/driving torque, the driver demand torque is decreased depending on the decrease in the accelerator pedal operation amount, the decrease rate of the driver demand torque depending on the decrease in the accelerator pedal operation amount is set to be smaller than the decrease rate for a case where the driver does not set a travelling speed, and the acceleration/deceleration is controlled based on the set driver demand torque, and when the accelerator pedal operation amount becomes zero subsequently, the acceleration/deceleration is controlled depending on the target braking/driving torque.

摘要： A braking force control method detects a wheel speed of a vehicle, generates a holding braking force for holding the stopped state of the vehicle, regardless of whether or not a brake is operated by a driver of the vehicle, when it is determined that the vehicle has stopped, based on the wheel speed detected in the state in which a braking force is applied to the vehicle, and delays the period in which the holding braking force is generated, in accordance with the friction coefficient of a road surface in the traveling path of the vehicle.

摘要： Information display is performed, in which recognizability of information regarding a driving support control is relatively good even in a situation where a driving load is relatively large, the information display not annoying a driver. A display controller displays a support state displaying image, which is an image having a configuration in which a vehicle image is superimposed on a mesh image as a mesh-like planar image, on a liquid crystal display device provided in a meter panel of a meter device. In addition, upon having determined that a driving support control implemented by a driving support device is operating, the display controller performs a display control to change a display mode of a mesh image portion of the support state displaying image, which is to be displayed on the liquid crystal display device, to a preset display mode.
