A system and method for real world autonomous vehicle perception simulation are disclosed. A particular embodiment includes: configuring a sensor noise modeling module to produce simulated sensor errors or noise data with a configured degree, extent, and timing of simulated sensor errors or noise based on a set of modifiable parameters; using the simulated sensor errors or noise data to generate simulated perception data by simulating errors related to constraints of one or more of a plurality of sensors, and by simulating noise in data provided by a sensor processing module corresponding to one or more of the plurality of sensors; and providing the simulated perception data to a motion planning system for the autonomous vehicle.

A system for tracking tread wear of a tire of a vehicle includes a processor configured to obtain a new tire rotational count value representing expected rotations of the tire over a set distance if the tire were new. A position tracking device is coupled to the vehicle and configured to track a distance traveled by the vehicle and report the distance to the processor. A wheel speed sensor is coupled to the vehicle and configured to track rotations of the tire. The processor determines a current tire rotational count value representing the number of rotations of the tire over the set distance. The processor then determines a tire tread wear value based on the new tire rotational count value and the current tire rotational count value. A display device is configured to display indicia based on the tire tread wear value.

A driving simulation test apparatus includes a movable body, a first translational drive portion that extends along a first direction, a first translational guide portion that extends along the first direction, and a plurality of first bases that extends along the first direction and is spaced from each other in a second direction. The first translational drive portion and the first translational guide portion are aligned in the second direction on each of the plurality of first bases, and the first translational drive portion includes a plurality of first translational drive portions arranged on each of the first bases.

A dynamometer load device applies a load to a dynamometer unit that is connected to a hub of a wheel of a motor vehicle and being movable. The dynamometer load device applies, in conjunction with steering of the motor vehicle, a load to the dynamometer unit turning along with the hub. The load is applied in a direction opposite to a turning direction of the dynamometer unit.

A vehicle inspection device for implementing a test on automatic braking performance of a test vehicle including an optical laser device for obstacle detection, in an inspection room three sides of which are surrounded by side walls, the vehicle inspection device comprising: a test instrument disposed at a side of the test vehicle; and a mirror unit that covers an upper face of the test instrument and upwardly guides light emitted from the optical laser device. The mirror unit may include a combination of a first plane mirror part disposed horizontally and a second plane mirror part disposed to be inclined.

Disclosed are a sensor mounting apparatus and associated method, e.g. for use in testing of a vehicle sensor in an anechoic chamber. The apparatus features a sensor mounting device for mounting the sensor and a vehicle part mounting device comprised of first, second and third frames. Each frame is movable in a different direction relative to the sensor and each other frame, e.g. either: adjustable forward and back, left and right, up and down, and/or via roll, yaw and pitch. The outermost third frame further includes an attachment means for holding a vehicle part (e.g. a vehicle fascia/bumper) in place and provision for further adjustment of the part relative to the sensor in use, e.g. via a pivot mounting enabling yaw movement.

A sensor assembly providing a physical property of a vehicle, e.g. tire pressure of a wheel of an aircraft, comprises electronic circuitry including a locking arrangement and sensor suited to sense the physical property and an exhaustable power source, e.g. a battery. For prolonged shelf life, a first and a second switch are functionally arranged between power source and circuitry. The second switch is controlled by the locking arrangement, whereas the first switch is controllable from outside the sensor assembly, e.g. by a magnetic field. The first switch is arranged to switch the power to the electronic circuitry, whereby the locking arrangement is powered, too. In consequence, the locking arrangement is capable to close the second switch. Thereafter, a further stimulus to the first switch will no more be capable to switch the sensor off, unless the locking arrangement enables it again by opening the second switch.
