Abstract
A vehicle includes a rotationally movable actuating element and a sensor arrangement for measuring an actuating angle of the actuating element. The sensor arrangement has a measuring acceleration sensor which is fastened to the actuating element, and a reference acceleration sensor which is fastened immovably to the vehicle. A method for measuring the actuating angle of a rotationally movable actuating element in a vehicle, a measuring arrangement configured to carry out a method for measuring, a computer program product and a provision apparatus for the computer program product, are also provided.
Claims16
A vehicle, comprising:
- a rotationally movable actuating element and a sensor arrangement for measuring an actuating angle of said actuating element;
- said sensor arrangement having:
- a measuring acceleration sensor fastened to said actuating element, and
- a reference acceleration sensor being separate from said measuring acceleration sensor and being fastened immovably to the vehicle;
- said sensor arrangement configured to:
- use said measuring acceleration sensor to take into account a direction of acceleration due to gravity aligned vertically to the center of the earth, to generate angle measurement data in a global coordinate system dependent on the actuating angle and a vehicle position, and
- use said reference acceleration sensor to take into account the direction of the acceleration due to gravity, to generate error measurement data in the global coordinate system dependent on the vehicle position;
- the vehicle configured for computer-aided calculation of the actuating angle from the angle measurement data, taking into account the measurement error measurement data;
- and
- the vehicle configured to calculate as the actuating angle at least one stop value for said actuating element, being measured upon an increase in the actuating angle prevented by a stop.
A method for measuring an actuating angle of a rotationally movable actuating element in a vehicle, the method comprising:
- using a sensor arrangement for measuring the actuating angle by:
- generating measurement data dependent on the actuating angle and a vehicle position, by taking a direction of acceleration due to gravity aligned vertically to the center of the earth into account, and generating the angle measurement data in a global coordinate system with a measuring acceleration sensor fastened to the actuating element, and
- generating measurement error measurement data dependent on the vehicle position, by taking the direction of the acceleration due to gravity into account, and generating the measurement error measurement data in the global coordinate system with a reference acceleration sensor fastened immovably to the vehicle and being separate from said measuring acceleration sensor;
- carrying out a computer-aided calculation of the actuating angle from the angle measurement data, by taking the measurement error measurement data into account;
- and
- calculating at least one stop value for the actuating element as the actuating angle, being measured upon an increase in the actuating angle prevented by a stop.
A measurement arrangement for carrying out a measurement method, the measurement arrangement comprising:
- a measuring acceleration sensor for generating measurement data in a global coordinate system linked to the earth dependent on an actuating angle of an actuating element and a vehicle position;
- a reference acceleration sensor disposed separate from said measuring acceleration sensor for generating measurement data in a global coordinate system linked to the earth dependent on the vehicle position;
- an output facility;
- a computer;
- a first interface between said measuring acceleration sensor and said computer;
- a second interface between said reference sensor and said computer;
- and
- an output interface between said output facility and said computer.
A non-transitory computer program product with program commands stored thereon that, when executed on a processor, carries out steps for measuring an actuating angle of a rotationally movable actuating element in a vehicle, comprising:
- using a sensor arrangement for measuring the actuating angle by:
- generating measurement data dependent on the actuating angle and a vehicle position, by taking a direction of acceleration due to gravity aligned vertically to the center of the earth into account, and generating the angle measurement data in a global coordinate system with a measuring acceleration sensor fastened to the actuating element, and
- generating measurement error measurement data dependent on the vehicle position, by taking the direction of the acceleration due to gravity into account, and generating the measurement error measurement data in the global coordinate system with a reference acceleration sensor fastened immovably to the vehicle and being separate from said measuring acceleration sensor;
- carrying out a computer-aided calculation of the actuating angle from the angle measurement data, by taking the measurement error measurement data into account;
- and
- calculating at least one stop value for the actuating element as the actuating angle, being measured upon an increase in the actuating angle prevented by a stop.
