  • Patent number: 12097770
    Abstract: A vehicle control apparatus controls a traveling motor coupled to wheels. The vehicle control apparatus includes a torque setting unit and a motor control unit. The torque setting unit sets a first target torque and a second target torque as target torques of the traveling motor. The first target torque changes based on an accelerator operation performed by a vehicle's driver. The second target torque changes more gradually than the first target torque. The motor control unit controls the traveling motor based on the first target torque or the second target torque. When the vehicle is moved forward without the accelerator operation, the torque setting unit sets the first target torque and the second target torque to a regenerative side. When the vehicle having been stopped is moved forward without the accelerator operation, the motor control unit controls the traveling motor based on the first target torque.

  • Patent number: 12060073
    Abstract: A control system for a vehicle capable of traveling in first and second traveling states is provided. The second traveling state requires an operation related to traveling by a passenger more than the first traveling state. The system changes, based on a traveling situation of the vehicle, an upper limit speed at which the vehicle can travel in the first traveling state. The system performs notification to the passenger of a request for a predetermined operation at a timing when a traveling speed of the vehicle reaches a predetermined speed when switching from the first traveling state to the second traveling state. A difference between the upper limit speed and the predetermined speed is increased in a case where the upper limit speed is high compared to a case where the upper limit speed is low.

  • Publication number: 20230339540
    Abstract: A moving body control apparatus includes a cancel control section performing control to cancel a lane change when a first cancel condition and a second cancel condition for cancelling the lane change are satisfied. When the first cancel condition is satisfied with the grip of an occupant on a manipulator being a prescribed level or greater, if a distance in a vehicle width direction between a moving body and a lane marker is a first distance threshold value or greater, the cancel control section judges that the second cancel condition is satisfied and cancels the lane change, and when the first cancel condition is satisfied with the grip being less than the prescribed level, if the distance is not less than a second distance threshold value greater than the first distance threshold value, the cancel control section judges that the second cancel condition is satisfied and cancels the lane change.

    Abstract: A vehicle includes a power source, a requested driving force calculator, and an actual driving force calculator, and a driving controller. The requested driving force calculator calculates a requested driving force on the basis of a driving operation. The actual driving force calculator calculates an actual driving force following the requested driving force, while limiting a rate of change in the actual driving force. The driving controller controls the power source to output the actual driving force calculated. The actual driving force calculator changes the rate of change in the actual driving force, on the basis of a difference between the requested driving force and the actual driving force, and a lapsed time of limiting the rate of change in the actual driving force.

  • Patent number: 11745600
    Abstract: A driving force controller for vehicle includes a driving force calculator and a driving controller. The driving force calculator calculates an instructed driving force, and includes a first determination unit that determines whether or not a predicted driving force satisfies a first condition. The predicted driving force assumes that the instructed driving force calculated on a first control cycle is changed at a rate of change calculated on the first control cycle, until a second control cycle. The first condition includes that a range between the instructed driving force calculated on the first control cycle and the predicted driving force at least partly cover a first range including a zero driving force. The driving force calculator imposes limitation on the rate of change in the instructed driving force to be calculated in the second control cycle, on the condition that the first condition is satisfied.

  • Publication number: 20230256956
    Abstract: A vehicle control apparatus to be applied to a vehicle includes an electric motor, a brake mechanism, and a control system. The control system increases a friction braking force of the brake mechanism while reducing a regenerative braking force of the electric motor, in deceleration traveling performed in a low vehicle speed range where a vehicle speed of the vehicle is less than a first threshold in a state in which an accelerator operation and a brake operation performed by a driver who drives the vehicle are canceled. The control system corrects correlation data between a control instruction value indicated to the brake mechanism and the friction braking force generated by the control instruction value, by using, as a trigger, a situation in which a change rate of a vehicle acceleration of the vehicle exceeds a second threshold in the deceleration traveling in the low vehicle speed range.
