  • Publication number: 20170203764
    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.

  • Publication number: 20150344034
    Abstract: In an apparatus, a first obtainer obtains a first travelling-condition parameter of a target vehicle. The first travelling-condition parameter shows one or more conditions under which the target vehicle is travelling on the road. A second obtainer obtains a second travelling-condition parameter of a preceding vehicle travelling on the road immediately ahead of the target vehicle. The second travelling-condition parameter shows one or more conditions under which the preceding vehicle is travelling on the road. A deviation calculator calculates a deviation between the first and second travelling-condition parameters. A behavior determiner determines a recommended behavior of the target vehicle in response to the calculated deviation. A controller controls a device, which is associated with a behavior of the target vehicle, according to the recommended behavior.

  • Patent number: 8676461
    Abstract: A control apparatus controls acceleration of a vehicle provided with a motive power generation apparatus and brake apparatuses. For the control, the control apparatus comprises calculation and actuating blocks. The calculation block calculates torque to be requested, based on a difference between an actual value of the acceleration and a target value thereof and a gain for feedback controlling the actual value of the acceleration to the target value thereof. The gain is differentiated in value between in a first case in which the brake apparatuses are used for the feedback control and a second case in which the brake apparatuses are not used for the feedback control. The actuating block actuates the motive power generation apparatus and the brake apparatuses based on the calculated torque. The value of the gain in the first case is made larger than the value of the gain in the second case.

  • Patent number: 8401757
    Abstract: A running control apparatus calculates a target driving or braking torque in a calculating block to control the vehicle driven or braked by this torque at a target speed against a running resistance changed with running circumstances of the vehicle. In a control block, when a driver-required braking torque based on the braking operation of the driver is smaller than the target braking torque, the running control for the vehicle is performed to brake the vehicle by the target braking torque. When the driver-required braking torque becomes higher than the target braking torque, the running control is stopped, and the driver manually brakes the vehicle by the driver-required braking torque. When the driver-required braking torque is decreased to be lower than the target braking torque or a predetermined braking torque corresponding to the release of the braking operation, the running control is restarted.

  • Patent number: 8292784
    Abstract: In a vehicle control device, a brake feedback control unit calculates a brake feedback torque Tfb-BK using a PID control model when a current state is a brake feedback use state. The brake feedback control unit stops the calculation of the brake feedback torque Tfb-BK when the current state is a brake feedback limitation state, and stores as an output value the brake feedback torque Tfb-BK that is output at a brake limitation start timing. At a brake limitation release timing, the brake feedback control unit restarts the feedback control using the stored brake feedback torque Tfb-BK as an initial value. The brake mechanism can thereby generate a predetermined brake torque of not more than 0 [N·m] immediately after the brake limitation release timing.

  • Patent number: 8214124
    Abstract: In a cruise control system for a vehicle, a cruise ECU calculates a cornering resistance applied to the vehicle based upon a steering angle, when a vehicle turns. The cruise ECU calculates a speed reduction amount as a correction vehicle speed based upon the cornering resistance. The cruise ECU subtracts the correction vehicle speed from a set vehicle speed to set a target vehicle speed so that the vehicle speed becomes lower as the cornering resistance is larger. The cruise ECU controls the vehicle speed to be within a permissible speed range of the target vehicle speed.
