A notification system includes at least one memory in which a program is stored and at least one processor combined with the at least one memory. The at least one processor is configured to execute, by executing the program, an acquisition process of acquiring at least one physical quantity from among acceleration, lateral acceleration, jerk, and vibration amplitude of a truck bed, and a notification process of sending a notification to a remote driving operator in response to a fact that the physical quantity exceeds a first threshold value set for each type of physical quantity.

A vehicle includes an engine, an accelerator pedal, and a controller. The controller is programmed to command torque to the engine based on a set speed of adaptive cruise control and is programmed to, in response to the adaptive cruise control being active, a measured lateral acceleration of the vehicle exceeding a user-defined lateral acceleration threshold during a road curve, and the accelerator pedal being released, reduce a speed of the vehicle below the set speed until the measured lateral acceleration is less than the lateral acceleration threshold.

An ADK is attachable to and removable from a VP and issues an instruction for autonomous driving to the VP. The VP includes a steering system for steering of the VP. (An ADS of) the ADK includes a compute assembly and communication module configured to communicate with the VP. The compute assembly obtains from the VP, a prescribed reference on which control of a wheel steer angle is premised, calculates the steer angle in accordance with a driving plan for autonomous driving based on the obtained prescribed reference, and transmits a wheel steer angle command indicating the calculated steer angle to the VP. When the attachable and removable ADK that issues the instruction for autonomous driving controls the VP, without storage of the prescribed reference on which control of the wheel steer angle is premised in advance in the ADK, control suited to a base vehicle can be carried out.

Systems and methods for vehicle motion control are provided. The method includes: calculating a correction factor using one of three different sets of operations when the vehicle is performing a limit handling maneuver, wherein the correction factor is calculated using a first set of operations when the vehicle is operating in an understeer state, calculated using a second set of operations when the vehicle is operating in an oversteer state, and calculated using a third set of operations when the vehicle is operating in a neutral steer state; adjusting a desired lateral acceleration and a desired yaw rate by applying the correction factor to account for a reduced level of friction experienced by the vehicle when traveling on a non-ideal friction surface; calculating optimal control actions based on the adjusted desired lateral acceleration and adjusted desired yaw rate; and applying the optimal control actions with vehicle actuators during vehicle operations.

A travel control device for a vehicle, includes: a lane information acquisition unit configured to acquire lane information; a steering control unit configured to control steering of the vehicle by executing lane travel control to make the vehicle travel along the lane; and a vehicle speed control unit configured to control a vehicle speed by executing constant speed travel control in which the vehicle is made to travel at a set vehicle speed and/or adaptive cruise control in which the vehicle is made to travel at a speed equal to or lower than the set vehicle speed so as to follow a preceding vehicle. The vehicle speed control unit is configured to control the vehicle speed during a turn of the vehicle by setting a vehicle speed upper limit value, which is set to different values depending on whether the lane travel control is being executed.
