Abstract: In an evacuation travelling assistance apparatus, a risk determining unit determines, when a driver is not in a state capable of appropriately performing driving operations, a risk involved in stopping at a location and a risk involved in passing through the location, for each of a plurality of locations that may serve as an advancing destination of the own vehicle, based on map information, own vehicle information, and peripheral environment information. An evacuation destination setting unit sets a location at which the risk involved in stopping at the location is lower than a predetermined reference as an evacuation destination, based on the determined risk. An evacuation route setting unit combines locations at which the risk involved in passing through the location is lower than a predetermined reference, based on the determined risk, and sets an evacuation route from the current position of the own vehicle to the evacuation destination.

Abstract: In assisting merging vehicles on the road, a own vehicle is accelerated to target speed on a first lane. The own vehicle accelerated to the target speed is caused to change a travel lane from the first lane into a second lane. A distance A from the own vehicle to a reference position is acquired in the first lane, and speed of the own vehicle is also acquired. A traveling distance B required for the own vehicle to stop is calculated under a condition where the own vehicle traveling at speed acquired starts to slow down at predetermined deceleration. Assisting in merging is performed, on condition that a value obtained by subtracting the calculated distance B from the acquired distance A is smaller than a predetermined threshold value during a period from a start time of the acceleration to a start time of changing the travel lane.

Abstract: The brake device for a vehicle generates two master pressures by controlling one single servo pressure to accurately control braking force. The pressure increasing characteristic is set based on the first pressure increasing characteristic obtained from the relationship between the servo pressure and the first master pressure upon increasing the servo pressure and the second pressure increasing characteristic obtained from the servo pressure and the second master pressure. The pressure decreasing characteristic is set based on the first pressure increasing characteristic obtained from the relationship between the servo pressure and the first master pressure upon decreasing the servo pressure and the second pressure decreasing characteristic obtained from the servo pressure and the second master pressure. Thus, the total braking force of the brake device is the sum of a braking force generated by the first master pressure and a braking force generated by the second master piston.

Abstract: When a brake switch is switched from OFF to ON, current is applied to a brake ECU, and a command to switch a master cylinder from a second state to a first state is issued after a lapse of preparation time, so that switching-time change suppression control is performed. A reservoir shutoff valve is closed, and duty control is performed on a communication control valve. The duty ratio is set to 1 when a switching-time control duration expires, and the communication control valve is placed in an open position, to establish the first state. Thus, since the communication control valve is duty-controlled during switching from the second state to the first state, change in the hydraulic pressure of an input chamber is suppressed, and change of the operating feeling is suppressed.

Abstract: A control apparatus for a vehicle includes processing circuitry. The processing circuitry calculates a target torque such that the greater the amount of brake operation is, the smaller the target torque becomes. The processing circuitry controls the drive motor such that the creep torque is smaller when brake operation is being performed by the driver than when the brake operation is not being performed by the driver. The control circuitry controls the brake device such that, when the brake operation is being performed by the driver, the brake torque approaches a target brake torque. The processing circuitry sets a decrease gradient of the creep torque to be smaller than a decrease gradient of the target torque when the brake operation amount is increased under a condition in which the creep torque is being output by the drive motor.
