In some examples, a controller determines a target condition of usage of a vehicle, and selects a parameter set from among a plurality of parameter sets based on the determined target condition of usage of the vehicle, the plurality of parameter sets corresponding to different conditions of usage of the vehicle, where each parameter set of the plurality of parameter sets includes one or more parameters that control adjustment of one or more respective adjustable elements of the vehicle. The controller transmits, to the vehicle, the selected parameter set to control a setting of the one or more adjustable elements of the vehicle.
Devices, systems, and methods for remote authorization of vehicle platooning
Systems and methods for coordinating and controlling vehicles, for example heavy trucks, to follow closely behind each other, or linking to form a platoon. In one aspect, on-board controllers in each vehicle interact with vehicular sensors to monitor and control, for example, relative distance, relative acceleration or deceleration, and speed. In some aspects, vehicle onboard systems supply various data (breadcrumbs) to a Network Operations Center (NOC), which in turn provides data (authorization data) to the vehicles to facilitate platooning. The NOC suggests vehicles for platooning based on, for example, travel forecasts and analysis of relevant roadways to identify platoonable roadway segments. The NOC also can provide traffic, roadway, weather, or system updates, as well as various instructions. In some aspects, a mesh network ensures improved communication among vehicles and with the NOC. In some aspects, a vehicle onboard system may provide the authorization data.
VEHICLE AND VEHICLE CONTROL INTERFACE
A vehicle is a vehicle on which an ADK is mountable. The vehicle includes: a VP that controls the vehicle in accordance with an instruction from the ADK; and a VCIB that serves as an interface between the ADK and the VP. The VP outputs a brake pedal position signal in accordance with an amount of depression of a brake pedal by a driver, and outputs a brake pedal intervention signal, to the ADK through the VCIB. The brake pedal intervention signal indicates that the brake pedal is depressed, when the brake pedal position signal indicates that the amount of depression is larger than a threshold value, and indicates beyond autonomy deceleration of the vehicle, when a deceleration request in accordance with the amount of depression is higher than a system deceleration request.

An anti-rollover apparatus and control method for heavy-duty vehicles with a pneumatic brake system includes an anti-yaw module, an anti-roll module, an electronic control unit (ECU) (10), a yaw velocity sensor (12), and a vehicle roll angle sensor (18). The ECU (10) controls solenoid valves (4, 9, 11, 19, and 24) to achieve braking of part of wheels to obtain anti-yaw torques and improve the yaw stability of the heavy-duty vehicles. The ECU (10) controls gas switch valves (21 and 22) to spray high-pressure gases recovered in brake chambers (1, 13, 16, and 26) out, anti-roll torques are obtained through the jet reactive force, and the roll stability of the heavy-duty vehicles is improved.
Vehicle dispatch support system, vehicle dispatch support method, and non-transitory recording medium
A vehicle dispatch support system includes a recording section at which comparison vehicle sensitivity information and candidate vehicle sensitivity information are recorded, the comparison vehicle sensitivity information being information relating to a driving sensitivity of a comparison vehicle that is a vehicle that a user has ridden in the past, and the candidate vehicle sensitivity information being information relating to a driving sensitivity of each of a plurality of candidate vehicles, a processor coupled to the recording section and configured to compute a sensitivity difference, which is a difference between the driving sensitivity expressed by the comparison vehicle sensitivity information and the driving sensitivity expressed by the candidate vehicle sensitivity information, and a display section configured to display sensitivity difference-related information, which is information based on the sensitivity difference.
Vehicle communications device and non-transitory computer-readable recording medium storing program
A dialog confirmation unit in a vehicle communication device calculates the deceleration of a vehicle on the basis of vehicle speeds, when the vehicle speed at an operation start time and the vehicle speed at a time when a certain time has elapsed since the operation start time have been obtained by a vehicle information acquisition unit. Next, the dialog confirmation unit calculates a change in distance on the basis of distances when a distance information acquisition unit has obtained the distance between the vehicle and an object in front at the operation start time and the distance at the time when a certain time has elapsed since the operation start time. Next, the dialog confirmation unit selects a dialog that corresponds to the deceleration and the change in distance, from among a plurality of dialogs.
VEHICLE CONTROL SYSTEM
A vehicle control system, includes: a travel control unit configured to generate a first control signal for controlling a direction control device of a vehicle to make the vehicle travel along a road shape; a stability control unit configured to generate a second control signal for controlling the direction control device to stabilize behavior of the vehicle when the behavior of the vehicle is in a prescribed unstable state; and an arbitration unit configured to receive the first control signal and the second control signal and to output at least one of the first control signal and the second control signal to the direction control device. When the arbitration unit is receiving the second control signal, the arbitration unit reduces a control amount corresponding to the first control signal.
Launch control method for a vehicle
A launch control method is provided for a vehicle having an accelerator, a brake and a continuously variable transmission (CVT). The method comprises determining: (i) a braking torque set by a vehicle operator by pressing a brake pedal of the vehicle; and (ii) a holding torque required to hold the vehicle in a stationary position. The method also determines that the operator has released the brake pedal. The brake is released whilst engaging a launch clutch of the CVT, wherein the launch clutch is engaged by increasing a clutch engagement pressure at a first pressure ramp rate, such that the sum of the braking torque and a clutch torque of the clutch remains equal to the holding torque. An acceleration torque requested by the operator via the accelerator is determined. The clutch engagement pressure is increased at a second pressure ramp rate when it is determined that the braking torque is substantially zero, such that the clutch torque is increased by the acceleration torque. A fixed minimum pressure ramp rate is stored, wherein the minimum pressure ramp rate increases the clutch engagement pressure towards a maximum engagement pressure. The current pressure ramp rate is compared with the minimum pressure ramp rate, and the clutch engagement pressure is switched to the minimum pressure ramp rate if the current pressure ramp rate is less than the minimum pressure ramp rate.
