摘要： When a motor vehicle is not in motion, an algorithm for establishing the initial zero point offset values for a yaw rate sensor as may be used in motor vehicle software control systems. The initial values are the manufactured values and are downloaded into the vehicle ECU at the time of the manufacture of the ECU. When the vehicle is waken at the vehicle assembly and the ignition is first turned on, the initial actual value of the zero point offset is stored both as a maximum and minimum value. At subsequent adjusting times when the vehicle is not moving, but the ignition is on, the spread between the maximum and minimum values are checked. If the spread becomes greater than a desired predetermined spread, the value, be it the maximum or minimum value reflects the measured value and the other value is adjusted to be within the desired spread. When the ignition is turned off and the vehicle is not moving, the zero point offset maximum and minimum values are stored in memory. The mean value is calculated to provide the new zero point offset value of the yaw rate sensor when the vehicle ignition is then turned on and the vehicle is not moving.

The calibration can include commanding, by the controller, a first actuator to move a second actuator to maximum engagement/disengagement positions indicating maximum engagement/disengagement of a park pawl with/from a park gear of a transmission. The calibration can include determining, at the controller, full engagement/disengagement positions for the second actuator based on the maximum engagement/disengagement positions. The controller can then control the engagement/disengagement of the park lock system using the full engagement/disengagement positions for the second actuator, respectively.

摘要： For a motor vehicle 10, a method for generating a map of a vehicle's dynamic steering ratio as a function of vehicle velocity and yaw rate. The steering ratio accounts for vehicle system compliance during dynamic maneuvers. The mapping of the steering ratio is used in an algorithm to estimate the vehicle's steering wheel angle while the vehicle is in a dynamic maneuver such as a turning maneuver. This estimation is based on the front wheel steer angles that are derived from the yaw rate and longitudinal velocity and the steering ratio.

摘要： A misalignment detection system (12) for steering system of an automotive vehicle (10) includes a controller (14) coupled to a velocity sensor (18), and a yaw rate sensor (20). The controller is also coupled to a memory (16) that is used to store a steering ratio memory map and a historic steering wheel angle. The controller (14) determines a base steering wheel angle when the vehicle velocity is at a predetermined velocity. The base steering wheel angle is a function of the vehicle velocity, the yaw rate, and the steering ratio. The controller compares the current steering wheel angle with a historic steering wheel angle to determine an error. An indicator (22) may be provided to the vehicle operator to signal the presence of the misalignment of the steering system.
