Vehicle path planning
A computing system can receive, in a vehicle, moving object information is determined by processing lidar sensor data acquired by a stationary lidar sensor. The moving object information can be determined using typicality and eccentricity data analysis (TEDA) on the lidar sensor data. The vehicle can be operated based on the moving object information.
CONTROL METHOD FOR AUTOMATIC HOLDING, A VEHICLE'S BRAKE SYSTEM AND A BRAKE CONTROL MODULE THEREOF
The present invention provides a control method for automatic holding, a vehicle's brake system and a brake control module thereof. The vehicle's brake system comprises two brake control modules and electromechanical brakes controlled by the brake control modules, a drive motor and a drive motor controller for controlling the drive motor. The control method comprises: after the vehicle transitions from moving to stationary, controlling the electromechanical brakes to continuously provide a brake torque, wherein the brake torque is a sum of the effective brake torque and a margin brake torque; and continuously outputting a drive-off signal to the drive motor controller to control the drive motor not to provide drive torque; until a driver requested drive torque is continuously increased to a critical torque which is close to the effective brake torque.
METHODS AND APPARATUS FOR COMPENSATING FOR UNIQUE TRAILER OF TRACTOR TRAILER WITH AUTONOMOUS VEHICLE SYSTEM
A method includes an initial trailer health assessment and real-time trailer health monitoring. The initial trailer health assessment includes autonomous pre-trip maneuvers of the autonomous vehicle during a first time period, and detecting a pre-trip vehicle health condition. A vehicle health score is calculated based on the pre-trip vehicle health condition. If the vehicle health score is at least a threshold value, real-time trailer health monitoring is performed during a trip of the autonomous vehicle during a second time period, by actively monitoring vehicle dynamics data and/or image data associated with the autonomous vehicle, to determine a fault condition of the autonomous vehicle. If the fault condition meets a first criteria, a control parameter and/or a travel plan of the autonomous vehicle is adjusted. If the fault condition meets a second criteria different from the first criteria, a signal is sent to cause the autonomous vehicle to cease movement.

Vehicle monitoring strategy for detecting unintended acceleration during speed control
A method detects unintended acceleration of a motor vehicle during a closed-loop speed control mode by determining external forces on the vehicle via a controller, and then calculating a desired acceleration using a measured vehicle speed and the external forces. The method includes determining an actual acceleration of the vehicle, including filtering a speed signal as a first actual acceleration value and/or measuring a second actual acceleration value using an inertial measurement unit (IMU). During the speed control mode, the method includes calculating an acceleration delta value as a difference between the desired acceleration and the actual acceleration, and then using the acceleration delta value to detect the unintended acceleration during the speed control mode. A powertrain system for the motor vehicle, e.g., an electric vehicle, includes the controller and one or more torque generating devices coupled to road wheels of the vehicle.

Techniques are described for estimating road friction between a road and tires of a vehicle. A method includes receiving, from a temperature sensor on a vehicle, a temperature value that indicates a temperature of an environment in which a vehicle is operated, determining a first range of friction values that quantify a friction between a road and tires of a vehicle based on a function of the temperature value and an extent of precipitation in a region that indicate a hazardous driving condition, obtaining, from the first range of friction values, a value that quantifies the friction between the road and the tires of the vehicle, where the value is obtained based on a driving related behavior of the vehicle, and causing the vehicle to operate on the road based on the value obtained from the first range of friction values.
