  • Patent number: 10814729
    Abstract: A vehicle alignment system is adapted to align a vehicle with a wireless power induction coil for wireless charging through use of magnetic resonant induction. The system includes a transmission line disposed in the parking slot so as to guide the vehicle to the wireless power induction coil for charging. The transmission line leaks a signal having an operating frequency that is detected to align the vehicle left-right in the parking slot when the vehicle is aligned for charging by the wireless power induction coil. At least two vehicle mounted antennas mounted on opposite sides of transmission line when the vehicle is aligned in the parking slot detect the operating frequency from the transmission line, and signal processing circuitry detects a relative signal phase between signals detected by the antennas. The relative phase differences between the detected signals from the antennas are representative of alignment of the vehicle with respect to the wireless power induction coil and the parking slot.

    Abstract: The driving support ECU performs a steering control for changing a steering angle in such a manner that an own vehicle travels along a target path. When a state in which holding state information does not satisfy a first condition continues for a first time threshold or more, the ECU starts a first alert and continues the steering control. The holding state information includes information indicative of a steering torque and represents a holding state of a steering handle by a driver. When a state in which the holding state information does not satisfy a second condition for a second time threshold or more after the first alert is started, the ECU starts a deceleration control. The second condition is a condition satisfied when the holding state information indicates that the driver holds the steering handle more firmly than when the holding state information satisfies the first condition.

A wheel angle adjuster is actuated by the operating element of the driver and/or by an electronic control unit that controls the automated lateral guidance of the vehicle so as to adjust a steering angle at the steerable wheels of the vehicle. In the process, a degree of coupling between at least one first part of the operating element and the wheel angle adjuster of the vehicle and/or between at least one first part of the operating element and a fixed position in the coordinate system of the vehicle can be modified depending on the degree of haptic contact between the driver of the vehicle and the aforementioned first part of the operating element.

  • Patent number: 10745014
    Abstract: An inter-vehicle calculation unit calculates a required inter-vehicle distance required between the own vehicle and forward/rear vehicles traveling in the lane to which the own vehicle moves during the lane change. The required inter-vehicle distance includes a first inter-vehicle distance and a second inter-vehicle distance. The first inter-vehicle distance is the distance required to allow the own vehicle or the forward/rear vehicles to adjust their velocity after the own vehicle changes lanes, and the first inter-vehicle distance is calculated by a first calculation unit. The second inter-vehicle distance is the distance required between the own vehicle and the forward/rear vehicles after the own vehicle or the forward/rear vehicles adjust their velocity, and the second inter-vehicle distance is calculated by a second calculation unit. A determination unit determines that the own vehicle can change lanes if the relative distance is equal to or greater than the required inter-vehicle distance.

  • Patent number: 10703407
    Abstract: When a steering angle reaches a first value close to a second value that defines a boundary of the maximum physical range of operation of a steering wheel, an ECU calculates a virtual end controlled variable that sharply increases a steering torque. The ECU calculates a second limit on the virtual end controlled variable and calculates a final limit (upper and lower limits) on an assist controlled variable by taking into account the second limit. When performing virtual end control, the ECU calculates the final limit on the assist controlled variable by using, as a first limit corresponding to the steering torque, a previous value held by upper and lower limit holders, instead of a present value calculated in accordance with the steering torque in a present calculation cycle.
