Abstract: A vehicle behavior control method includes: selecting a center of gravity point at which behavior control for a vehicle is to be performed; setting a target roll behavior value and a target pitch behavior value at the selected center of gravity point such that behavior of the selected center of gravity point is less than a predefined reference value; calculating a target roll moment corresponding to the target roll behavior value and a target pitch moment corresponding to the target pitch behavior value; generating a control signal to be transmitted to at least one actuator for following the target roll moment and the target pitch moment; and transmitting the control signal to the at least one actuator to perform control such that the behavior at the selected center of gravity point is less than the predefined reference value.

Abstract: A system for navigating a vehicle may include a processor programmed to receive an output provided by a vehicle sensor, and determine a navigational maneuver for the vehicle along a road segment based on the output provided by the vehicle sensor. The processor may also be programmed to determine a yaw rate command and a speed command for implementing the navigational maneuver. The processor may also be programmed to determine a first vehicle steering angle based on the yaw rate and speed commands using a first control subsystem, and determine a second vehicle steering angle based on the yaw rate and speed commands using a second control subsystem. The processor may further be programmed to determine an overall steering command for the vehicle based on a combination of the first and second steering angles, and cause an actuator associated with the vehicle to implement the overall steering command.

Abstract: An example calibration system includes a speed sensor, a steering angle sensor, a calibration unit, and a controller. In some implementations, the calibration unit generates a first plot of a first series of first yaw rate estimates over time based upon signals from the speed sensor and the steering angle sensor, generates a second plot of a second series of second yaw rate estimates over the time based upon signals from at least one inertial measurement unit and compares the first plot and the second plot to determine a steering offset bias that minimizes differences between the first plot and the second plot. The controller outputs control signals to adjust at least one of a steering and propulsion of the tractor based on the steering offset bias. In some implementations, the controller determines an updated tire radius for a tractor tire based upon different estimated tractor speeds.

Abstract: A platooning control method includes: determining whether a preceding vehicle, which is located in front of a host vehicle, has entered a slope section when a plurality of vehicles are moving on a road, acquiring longitudinal distance information between the host vehicle and the preceding vehicle using a Dead-Reckoning (DR) sensor of the host vehicle upon determining that the preceding vehicle has entered the slope section, and performing platooning control by the host vehicle with the plurality of vehicles in the slope section using the longitudinal distance information acquired by the DR sensor and speed information.

Abstract: A vehicle behavior control apparatus, which can improve vehicle behavior stability, is provided. The vehicle behavior control apparatus includes a motor and a pitch angle control apparatus. The motor is connected to at least one of a front wheel and a rear wheel of a vehicle. The pitch angle control apparatus is configured to execute pitch angle control to adjust a pitch angle through adjusting a driving force of each of the front wheel and the rear wheel. The pitch angle control apparatus performs the pitch angle control when a driving torque of the motor belongs to a first driving region not including zero and limits the pitch angle control when the driving torque of the motor belongs to a second driving region. The second driving region is a region before and after positive and negative torque switching of crossing zero.

Abstract: Some embodiments may provide a method for a desired operating environment. A signal to place a vehicle in a designated mode corresponding to a desired operating environment may be received. The designated mode may include modifications to one or more default operating characteristics of the vehicle. The modifications may be while the vehicle is in parked mode and a vehicle access key associated with the vehicle is within proximity of the vehicle. In response to receiving the signal, characteristics of the vehicle to be modified in order to create the desired operating environment may be identified. The default operating characteristics may relate to lighting or displays controlled by the vehicle, sounds controlled by the vehicle, or a passive entry system of the vehicle. One or more settings of the vehicle to change the default operating characteristics of the vehicle while in the designated mode may be modified.

Abstract: A system and corresponding method for autonomous driving of a vehicle are provided. The system comprises at least one neural network (NN) that generates at least one output for controlling the autonomous driving. The system further comprises a main data path that routes bulk sensor data to the at least one NN and a low-latency data path with reduced latency relative to the main data path. The low-latency data path routes limited sensor data to the at least one NN which, in turn, employs the limited sensor data to improve performance of the at least one NN's processing of the bulk sensor data for generating the at least one output. Improving performance of the at least one NN's processing of the bulk sensor data enables the system to, for example, identify a safety hazard sooner, enabling the autonomous driving to divert the vehicle and avoid contact with the safety hazard.

Abstract: Provided is a system and method for imitating control signals from physical input mechanisms of a vehicle. Examples of such physical input mechanisms include a gas pedal, a brake pedal, and the like. In one example, the method may include receiving an acceleration value from a planning system associated with a vehicle and a state of the vehicle from a state estimation system, converting, via a software control node, the acceleration value and the state of the vehicle into at least one of an engine torque value and a brake pressure value, generating a control signal for controlling a speed of the vehicle based on the at least one of the engine torque value and the brake pressure value, and transmitting the control signal to a control system of the vehicle.

Abstract: Aspects of online camera calibration for autonomous driving systems are described herein. The aspects may include a wheel odometer configured to measure a current speed of a moving vehicle, a speed monitor configured to determine that the current speed of the moving vehicle is high or low, and a camera calibrator configured to calibrate, while the vehicle is moving, at least one front camera of the moving vehicle according to a position of a vanishing point of two lane lines when the current speed is high. When the current speed is low and the vehicle is still moving, the camera calibrator may be further configured to calibrate multiple side and rear cameras of the moving vehicle according to a pose graph that includes relative poses of the multiple side and rear cameras.
