摘要： This disclosure describes systems and methods for hands-free liftgate activation. An example method may include receiving a liftgate activation signal. The example method may also include receiving first data from a sensor of a vehicle at a first time and second data from the sensor at a second time. The example method may also include determining that a first difference between a second value associated with the second data and a first value associated with the first data is greater than a first threshold amount. The example method may also include disabling, based on the determination that the first difference is greater than the first threshold amount, activation of a liftgate of the vehicle. The example method may also include receiving third data from the sensor. The example method may also include determining that a second difference between a third value associated with the third data and the first value is less than a second threshold amount. The example method may also include enabling, based on the determination that the second difference is less than the second threshold amount or a determination that a first timer has elapsed, activation of the liftgate.

摘要： A vehicle including an active front steer system including a locking mechanism having a solenoid actuated locking pin and a spring for biasing the pin toward an extended or locked position for engaging a locking disc of the active front steer system wherein the active front steer system further includes a current sensor for sensing the motion of the pin of the solenoid when the engine of the vehicle is shut down and pulse width modulated current to the solenoid is reduced and when the pin movement is sensed, the pulse width modulated current is increased (fed forward duty cycle) to reduce the movement of the pin to reduce the noise made when the metal pin makes when contacting the metal locking disc. The end of the pin and/or the locking disc may also include an insulating material to further reduce any remaining noise made when the metal pin makes when contacting the metal locking disc.

摘要： A system for a vehicle includes a gear and a plate fixed to the gear. The gear is driving by a motor for providing relative rotation between a steering wheel and steering shaft of the vehicle in an adaptive front steering system. The system includes a solenoid including a coil and a pin moveable relative to the coil to engage the plate based on a signal. A sensor is configured to detect a change in current through the coil associated with initial movement of the pin relative to the coil. The system includes a controller programmed to change the duty cycle signal in response to the change in current to slow movement of the pin to reduce or eliminate a clicking noise associated with the pin seating in an extended position or retracted position.

摘要： Methods, apparatus, and articles of manufacture to correct clear vision errors in a vehicle steering system are disclosed. An example apparatus includes a first sensor and a second sensor to measure a current position of a steering column and a current position of a steering wheel in a vehicle steering system. The example apparatus further includes a non-uniformity manager to map the current position to an offset, and an active steering system to apply the offset to adjust the current position of the steering wheel to a nominal position of the steering wheel to compensate for a clear vision error.
