Vehicle travel control device

A vehicle travel control device executes trajectory following control to make the vehicle follow a target trajectory. A delay time represents control delay of the trajectory following control. A delay compensation time is at least a part of the delay time. The trajectory following control includes: displacement estimation processing that estimates a displacement of the vehicle in the delay compensation time; and delay compensation processing that corrects a deviation between the vehicle and the target trajectory based on the estimated displacement to compensate the control delay. The displacement estimation processing is effective in an effective period and ineffective in an ineffective period. When the ineffective period is included in the delay time of the trajectory following control, the displacement estimation processing is executed in a temporary mode by using sensor-detected information in the effective period without using the sensor-detected information in the ineffective period.

METHOD AND DEVICE FOR CONTROLLING PEDALS OF A VEHICLE

The present invention relates to a method for operating a driver model for controlling a vehicle. The driver model comprises a vehicle module (203) which determines an accelerator pedal position to be set on the vehicle. In addition, the vehicle module (203) determines a required power as a component of a total power, which total power can be generated by a drive system of the vehicle, wherein the required power corresponds to a power that is necessary for moving the vehicle at a required speed and/or a required acceleration (311) along a predefined road course. The method according to the invention further provides for a value (313) of a permissible pedal position to be assigned to the required power and for the value (313) of the permissible pedal position to be transmitted to the driver model in order to control the vehicle.

Driving force control apparatus for vehicle
11479254 · 2022-10-25 · ·

The driving force ECU calculates a restricted driving force for a driving force restricting control, by using a Proportional-Integral-Differential control formula which utilizes a difference between a target acceleration varied depending on a vehicle speed and an actual acceleration of the vehicle. The driving force ECU adjusts (changes) a proportion gain K1 of the Proportional-Integral-Differential control formula based on an inclination angle θ of a road in such a manner that a value of the proportion gain K1 used when the inclination inclination angle θ is relatively large is smaller than a value of the proportion gain K1 used when the inclination inclination angle θ is relatively small. The driving force ECU performs a driving force restricting control by selecting, as a target driving force used for the driving force restricting control, a pedal required driving force or the restricted driving force, whichever is smaller.

Speed control device, automatic navigation system and method of controlling speed

A speed control device which is satisfactory in response and tracking to a speed setting, and can adjust an acceleration-and-deceleration feel according to preferences, is provided. The speed control device 6 controls a speed of a ship so that the speed automatically follows a speed setting set by a ship operator. The speed control device 6 includes a target speed setting module 63 and a change rate adjusting module 64. The target speed setting module 63 sets a target speed that is a target of the speed of the ship to follow, for every unit time, according to the speed setting, to change the target speed based on a given rate of change. The change rate adjusting module 64 decreases the rate of change by adjusting the rate of change at multiple stages, when the target speed set by the target speed setting module 63 approaches the speed setting.
