A vehicle controller includes a memory configure to store a first map representing information on a road and a second map representing information on the road less accurately than the first map; and a processor configured to determine whether an involvement requirement for requesting a driver of a vehicle to be involved in driving the vehicle is satisfied, and give notification of a request for involvement in driving via a notification device provided in the vehicle interior when the involvement requirement is satisfied. The processor makes the involvement requirement less strict when autonomous driving control of the vehicle is based on the second map than when autonomous driving control of the vehicle is based on the first map.

A vehicle control device has a processor configured to determine whether or not a driver is attempting to move a vehicle from a traveling lane in which the vehicle is traveling to an adjacent lane, based on a monitor image taken of an area near a driving seat, and to activate the engine when it has been determined that the driver is attempting to move the vehicle from the traveling lane to the adjacent lane and the engine is stopped with drive power being obtained using the electric motor, wherein the vehicle is accelerated using the drive power of the engine when the engine is activated, if movement of the vehicle from the traveling lane to the adjacent lane has been requested by the driver.

Vehicle control device, storage medium for storing computer program for vehicle control, and method for controlling vehicle

A vehicle control device has a processor configured to set a target torque as a target for driver torque at which generation of anti-torque on a steering wheel is to be initiated, based on a reference torque as a reference for driver torque at which generation of anti-torque is to be initiated against the driver torque produced by operation of the steering wheel by a driver, and a current correction value for the reference torque, to count a number of deviations from a lane marking line of a lane in which the vehicle is traveling while the driver torque exceeds the target torque, and to calculate a new correction value for the reference torque based on a correction coefficient that is set based on the number of deviations, wherein the next target torque is set based on the reference torque and the new correction value for the reference torque.

A vehicle control device comprises a processor configured to set a reference lateral position, based on an intervehicular distance between the vehicle and another vehicle traveling on an adjacent lane, determine a target lateral position based on the reference lateral position and a current correction value for the reference lateral position, when the intervehicular distance falls below a predetermined reference distance, count a number of times that the lateral position of the vehicle in the traveling lane has been changed from the target lateral position, and calculate a new correction value based on a correction coefficient determined based on the number of changes and an amount of change in the lateral position of the vehicle that has changed from the target lateral position, wherein the next target lateral position is determined based on the reference lateral position and the new correction value.

A device for proposing autonomous driving includes a processor configured to identify an autonomously travelable section in which a vehicle is capable of traveling under autonomous driving control, make a proposal for travel under autonomous driving control to a driver of the vehicle via a notification device when a proposal determination value corresponding to the length of the identified autonomously travelable section satisfies a first proposal criterion, stop proposing travel through the autonomously travelable section under autonomous driving control to the driver when the proposal determination value corresponding to the length of the identified autonomously travelable section does not satisfy the first proposal criterion, and add a predetermined addition value to the proposal determination value corresponding to the length of the identified autonomously travelable section when an action of the driver to consent to the proposal for travel under autonomous driving control to the driver is not detected.

Device, method, and computer program for proposing autonomous driving

A vehicle control device has a processor configured to estimate whether or not a driver is attempting to begin vehicle travel after a vehicle has been activated, based on a photographed image of an area near a driving seat, and to control an electrical oil pump to supply a second hydraulic pressure that is lower than a first hydraulic pressure which allows operation of a transmission having a frictional engagement element that can be engaged and disengaged by hydraulic pressure, when it has been estimated that the driver is not attempting to begin vehicle travel, or to control the electrical oil pump to supply the first hydraulic pressure to the transmission, when it has been estimated that the driver is attempting to begin vehicle travel.

A vehicle control device has a processor configured to determine a set speed for a vehicle representing a target speed based on a speed limit of a road, and a current correction value corresponding to the speed limit of the road, count a number of changes the set speed for the vehicle has been changed by a driver, and calculate a new correction value for the set speed for the vehicle based on a correction coefficient determined based on the number of changes, and speed difference between the set speed for the vehicle after change and the speed limit of the road, each time the number of changes has been counted, wherein the next set speed for the vehicle is determined based on the speed limit of the road on which the vehicle is traveling and the new correction value corresponding to the speed limit of the road.

A transmission controller includes a processor configured to set acceleration/deceleration start timing at which a vehicle starts accelerating or decelerating, based on at least one of a sensor signal representing the situation around the vehicle, the current position of the vehicle, a map including information on a road being traveled by the vehicle, and operation of the vehicle by a driver, downshift a second transmission of a power train including two motors and an engine before the acceleration/deceleration start timing, and control the power train to vary first and second gear ratios of a first transmission so as to keep the RPM of the engine constant. The first transmission is capable of steplessly varying the first and second gear ratios, which are gear ratios between one of the motors and the engine and between the other motor and the engine, respectively.
