System and method for vehicle control in tailgating situations

A computer-implemented method for braking control of a host vehicle includes detecting a panic brake operation based on a change of a braking pressure of a braking system of the host vehicle with respect to time. The method includes detecting a second vehicle driving behind the host vehicle and in the same lane as the host vehicle, and determining a time-to-collision value between the host vehicle and the second vehicle. Further, the method includes determining a deceleration rate of the host vehicle based on a driver braking pressure provided by operation of a brake pedal of the braking system. The method includes controlling the braking system based on the time-to-collision value and the deceleration rate.

Method for controlling neutral gear of automatic transmission

Disclosed is a method for controlling a neutral gear of an automatic transmission. The method includes: when a neutral gear control function of the automatic transmission is in an activated state, an automatic Transmission Control Unit (TCU) collects information on a pressure of a brake main cylinder, a state of a brake pedal, and whether an autohold function is in an activated state or not; and when the pressure of the brake main cylinder is smaller than a pressure threshold P.sub.3 of the neutral gear control function and the autohold function is in an inactivated state, or when the brake pedal is in an unstamped state and the autohold function is in the inactivated state, the automatic TCU controls the neutral gear control function to exit from the activated state.

Devices, systems, and methods for generating travel forecasts for vehicle pairing

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.

Method for assisting a driver of a single-track motor vehicle in order to drive through a bend safely

A method is provided for assisting a driver of a single-track motor vehicle during a drive in order to drive through a bend safely. In the method, at least one current driving state variable and driver-specific driving dynamics variables are compared with an approaching driving situation and, if a danger threshold value is reached or exceeded, a warning signal is output. The current speed of the motor vehicle is sensed by a speed sensor and transmitted to a computerand memory unit as the current driving state variable. Both previously reached inclined positions of the single-track motor vehicle and previously reached brake pressures and/or brake pressure gradients are stored by the computer-and-memory unit as the driver-specific driving dynamics variables. In order to evaluate the approaching driving situation, a bend radius of a curve to be driven through next is determined via a navigation unit and is transmitted to the computerand memory unit.

Method for operating a drive train of a motor vehicle in an inclined position

A method for operating a drive train of a motor vehicle in an inclined position, in particular an agricultural or municipal utility vehicle. A connection between a prime mover and at least one drive axle of the motor vehicle is automatically disconnected as part of a function upon actuation of a service brake for stopping the motor vehicle monitored by at least one sensor. To avoid uncontrolled backward rolling, provision is made that a maximum brake pressure applied to achieve or maintain the standstill of the motor vehicle is determined and monitored by continually measuring a brake pressure applied by the service brake. Upon the brake pressure falling below the maximum brake pressure minus a pre-definable pressure difference, the function is automatically deactivated and thus the connection is automatically re-established between the prime mover and the at least one drive axle.

20200180632 · 2020-06-11 · ·

The present invention provides a vehicle control method capable of suppressing an increase in the frequency of stopping and restarting of the engine when the braking device is activated at the self-driving mode. When the operation mode is set as self-driving, the braking device is activated in accordance with a system deceleration request to keep an actual vehicle-speed at a target vehicle-speed or change the actual vehicle-speed at the target vehicle-speed or lower depending on environment surrounding the vehicle. Further, a braking amount is estimated, the braking amount is a magnitude of a braking force generated from the activated braking device. When the braking amount is an engine-stopping enabling threshold or more, enabling stopping is allowed. When the braking amount is less than the engine-stopping enabling threshold, enabling stopping is not allowed.

Method of operating the power train of a vehicle

A method of operating a drive-train (1) of a motor vehicle, in particular an agricultural or municipal utility vehicle, having a drive engine (2), a motor vehicle transmission (4) and at least one drive axle (6). A connection between the drive engine (2) and the at least one drive axle (6) of the motor vehicle is separate automatically by way of a function, and a service brake (11) of the motor vehicle has to be actuated for activation of the function.
