Motion can be induced at a vehicle, e.g., by actuating components of an active suspension system, and first sensor data and second sensor data representing an environment of the vehicle can be captured at a first position and a second position, respectively, resulting from the induced motion. A second sensor can determine motion information associated with the first position and the second position. Calibration information about the sensor, the first sensor data, and the motion information can be used to determine an expectation of sensor data at the second position. A calibration error can be the difference between the second sensor data and the expected sensor data.

A program and a control device capable of calibrating a detection value of a sensor that detects contact with a steering wheel are provided. The program in accordance with the present invention is characterized by causing a computer to execute processing of distinguishing whether or not a user is on a driver's seat of a vehicle; acquiring, from a sensor (21) that converts contact with a steering wheel (2) into an electric signal for detection, a detection value of the detected electric signal; determining whether or not a difference between the detection value acquired when it has been distinguished that the user is not on the driver's seat, and a reference value is equal to or larger than a threshold value; and setting the detection value as the reference value when it has been determined that the difference is not equal to or larger than the threshold value.

An orientationally flexible bump sensor is disclosed. The system includes at least one bump sensor mounted to a vehicle, the at least one bump sensor comprising at least two axes of measurement. A computer processor is configured to evaluate the at least two axes of measurement to determine which axis of the at least two axes of measurement has a highest magnitude vector and determine a gain value to cause the highest magnitude vector to be approximately 1g. The computer processor will assign the gain value to the axis with the highest magnitude vector, such that the gain value is applied to each measurement generated by the axis with the highest magnitude vector.

A calibration device includes: a first coefficient calculation unit, a first output unit, an ideal value calculation unit, a second coefficient calculation unit configured to calculate a second coefficient by dividing a second output value by the ideal value, the second output value being an actual output value of the detector when the extension/contraction amount of the suspension device is the first extension/contraction amount, and a calibration unit configured to calculate a calibration value which is an output value after calibration of the detector when the suspension device has the minimum extension/contraction amount, by using the second output value, the first extension/contraction amount, the operation amount, the first output value, and the second coefficient.

Embodiments of the present invention provide a control system (100) for determining a suspension calibration of a vehicle (800). The control system (100) has one or more controllers (120) that receive route data indicative of a route ahead of the vehicle (800). One or more processors (130) determine, from the route data, a prediction of a first acceleration at a first location (320) ahead of the vehicle (800) and a second acceleration at a second location (330) ahead of the first location(320). The one or more processors (130) determine a suspension calibration of the vehicle (800) in dependence on the second acceleration. The actual acceleration of the vehicle (800) is measured at the first location (320) and compared with the first acceleration. If the measured and first acceleration are within a predetermined tolerance, the processor (120) produces a suspension control signal at output (121) which is received by a suspension controller (140) to apply the suspension calibration prior to the vehicle (800) arriving at the second location (330).

A system for controlling vehicle ride height include a suspension controller. The suspension controller is coupled to a motion sensor attached to a chassis of a vehicle and additional motion sensors each attached to a suspension member of the vehicle that pivots relative to the chassis. The suspension controller receives motion sensor data from the motion sensors and determines relative angular position of each suspension member as a function of motion sensor data received from the motion sensor attached to the chassis and motion sensor data received from the motion sensor attached to the suspension member. The suspension controller adjusts an air suspension based on the relative angular position. Other embodiments are described and claimed.

A method for a sensor assembly of a vehicle that includes self-calibration of the vehicle variable sensor of the sensor assembly, the actual location and/or the actual position of the sensor assembly being automatically ascertained and compared with at least one setpoint location and/or setpoint position for the at least one operating routine of the sensor assembly. Outputting an error message if the actual location and/or actual position automatically ascertained does not essentially match any of the at least one setpoint locations and/or setpoint positions or if the actual location and/or actual position automatically ascertained does essentially match one of the at least one setpoint locations and/or setpoint positions then storaging the operating routine of the sensor assembly correlating to this setpoint location and/or setpoint position of the sensor assembly for a subsequent operation of the self-calibrated vehicle variable sensor of the sensor assembly.

A level adjustment system of a vehicle, comprising an electric engine a transmission driven by the electric engine; and a controller programmed to identify a motor current from the electric engine during an upward adjustment or downward adjustment of the vehicle, wherein the controller is further programmed to determine an actuator force generated by an actuator unit utilizing the motor current.
