ABNORMALITY DETERMINATION DEVICE, ABNORMALITY DETERMINATION METHOD, VEHICLE STATE ESTIMATION DEVICE, AND NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM
In an abnormality determination device for determining presence or absence of an abnormality of a 6-axis inertial measurement sensor installed in a vehicle to detect a forward-backward acceleration, a lateral acceleration, a vertical acceleration, a roll rate, a pitch rate, and a yaw rate of the vehicle, the abnormality determination device includes: a 3-axis inertial measurement sensor that detects the forward-backward acceleration, the lateral acceleration, and the yaw rate; and an abnormality determination unit that determines presence or absence of an abnormality of the 6-axis inertial measurement sensor, wherein the abnormality determination unit determines the presence or absence of an abnormality of the 6-axis inertial measurement sensor by comparing the forward-backward acceleration, the lateral acceleration, and the yaw rate acquired by the 6-axis inertial measurement sensor with the forward-backward acceleration, the lateral acceleration, and the yaw rate acquired by the 3-axis inertial measurement sensor, respectively.
VEHICLE DRIVE ASSIST APPARATUS
A vehicle drive assist apparatus includes a traveling environment information acquisition unit, a traveling state information acquisition unit, and a traveling control unit. The traveling environment information acquisition unit acquires traveling environment information. The traveling state information acquisition unit acquires traveling state information. The traveling control unit includes a malfunction detector and a takeover request processor. The malfunction detector detects a malfunction in the traveling environment information acquisition unit and the traveling state information acquisition unit. The takeover request processor executes a takeover request process for manual driving in a case where the malfunction is detected. The takeover request processor includes a waiting time measurement section and an output restricting section. The waiting time measurement section measures a waiting time from detection of the malfunction to transition to the manual driving. The output restricting section restricts an output of a drive source during the waiting time.
Data recorders of autonomous vehicles
Systems, methods and apparatus to collect sensor data generated in an autonomous vehicle. Sensors of the vehicle generate a sensor data stream that is buffered, in parallel and in a cyclic way, in a first cyclic buffer and a larger second cyclic buffer respectively. An advanced driver assistance system of the vehicle generates an accident signal when detecting or predicting an accident and provides a training signal when detecting a fault in object detection, recognition, identification or classification. The accident signal causes a sensor data stream segment to be copied from the first cyclic buffer into a slot of a non-volatile memory, selected from a plurality of slots in a round robin way. The training signal causes a sensor data stream segment to be copied from the second cyclic buffer into an area of the non-volatile memory outside of the slots reserved for the first cyclic buffer.
System and method for collaborative sensor calibration
The present teaching relates to method, system, medium, and implementations for sensor calibration. An ego vehicle determines whether a sensor deployed on the ego vehicle to facilitate autonomous driving of the ego vehicle needs to be calibrated and sends, if it is determined that the sensor needs to be calibrated, a request for assistance in collaborative calibration of the sensor, with a first position of the ego vehicle or a first configuration of the sensor with respect to the ego vehicle. When a response of the request is received, an assisting vehicle is indicated to travel to be near the ego vehicle to facilitate the calibration of the sensor by collaborating with the moving ego vehicle and the ego vehicle coordinates with the assisting vehicle to enable the sensor to acquire information of a target present on the assisting vehicle for the collaborative calibration of the sensor.
AUTONOMOUS DRIVING SYSTEM AND ABNORMALITY DETERMINATION METHOD
