A method of decreasing vibration during release of a stop gear of a vehicle can be applied to an eco-friendly vehicle for decreasing vibration generated when a driver releases a P step of a gear lever while torsion occurs in a drive shaft of the vehicle. Reaction force torque of a driving motor is controlled so as to output reaction force that has been generated in a parking sprag by a driving motor when torsion occurs in the drive shaft after entrance of the gear lever into the P step, so as to decrease vibration generated because torsion reaction force of the drive shaft vanishes at the same time.

Provided is a vehicle stop support system for supporting vehicle stop in an emergency condition. The vehicle stop support system detects a physical abnormality of a driver; sets a stop point; and controls a vehicle to travel to the stop point and stop at the stop point. The system is operable to: calculate, with respect to each of a plurality of stop point candidates, a first index value which increases with an increase in a lateral acceleration, a second index value which increases with an increase in rear-end collision risk, a third index value based on the detected abnormality, and a gross index value, wherein the gross index value is obtained by subjecting the first, second, and third index values to weighting, and summing the resulting weighted index values; and then set one of candidates which is smallest in terms of the gross index value, as the stop point.

The invention relates to a state control system and method for a vehicle with a battery to be swapped. The system includes: a central gateway, a vehicle state control module, and a vehicle state monitoring module that are communicatively connected, where after receiving a state-to-be-adjusted signal, the central gateway sends a control instruction to the vehicle state control module and/or the vehicle state monitoring module; the vehicle state control module and/or the vehicle state monitoring module adjust/adjusts, according to the control instruction, a state of the vehicle with a battery to be swapped; and the vehicle state monitoring module obtains an adjusted vehicle state of the vehicle with a battery to be swapped, and determines whether the vehicle state is a preset vehicle state required for a battery swap process of the vehicle with a battery to be swapped. In the invention, various control modules in the vehicle with a battery to be swapped are communicatively connected, to implement automatic adjustment of a state of the vehicle, so that the state of the vehicle with a battery to be swapped can be quickly and accurately adjusted to a state required for a battery swap process.

A start-stop vehicle includes an engine configured to automatically stop and start during travel. The vehicle further includes a gear lever, a brake pedal, and a controller. The controller is programmed to restart the engine or inhibit restarting of the engine depending upon one or more sets of conditions of the vehicle. A method is also present for operating the vehicle based upon the one or more sets of conditions.

A vehicle controller is provided, including: a drive source generating drive torque in a vehicle; a brake applying braking force to wheels; a drive torque control unit controlling the drive torque; a braking force control unit controlling the braking force; an EPB operation instructing unit instructing operation of an electric parking brake; and an electric parking unit, including the parking brake and a driver driving the electric parking brake to cause the electric parking brake to operate in response to the EPB operation instructing unit. The drive torque control unit implements, based on an operation instruction status of the EPB operation instructing unit, driving force restriction control to restrict the drive torque, and when an operation instruction status becomes unknown while the driving force restriction control is implemented, the driving force restriction control is continued regardless of the operation status of the EPB operation instructing unit.

An assistance System for a vehicle for providing an emergency stop assistance function that includes an execution device to execute the emergency stop assistance function using at least one of a plurality of activation stages; a detection device for automatic detection of driver inactivity, in order to activate the emergency stop assistance function using a first stage selection of the activation stages; a triggering device for monitoring an operating element of an electrical parking brake or a parking lock of a transmission of the vehicle, in order to activate the emergency assistance function using a second stage selection of the activation stages, which differs from the first stage selection, in the case of a manual activation of the operating element.

A vehicle control apparatus that is mounted in a vehicle issues a warning to a driver of the vehicle to stop the vehicle in a case where the collision has occurred between the vehicle and an object. The vehicle control apparatus stops the vehicle regardless of an operation by the driver after issuing the warning to the driver, in a case where the vehicle is not detected to be stopped. Thus, while giving a priority on prompting the driver to voluntarily stop the vehicle, it is possible to prevent the driver from fleeing a scene of the accident or the like.

In one aspect, a system for monitoring a level of hydraulic fluid in an agricultural sprayer includes a drive system, a hydraulic fluid system, and a fill level sensor. The system also includes a computing system communicatively coupled to both the drive system and the fill level sensor. The computing system is configured to monitor the level of hydraulic fluid within the hydraulic fluid reservoir based on data received from the fill level sensor. The computing system is further configured to detect a leak condition in the hydraulic fluid system based at least in part on the monitored level of the hydraulic fluid within the hydraulic fluid reservoir and control an operation of the drive system to reduce the ground speed of the agricultural sprayer in response to detecting the leak condition.

A vehicle control device including an electronically controlled throttle device and configured to control a vehicle for supplying a hydraulic pressure to a friction engaging element of a transmission on the basis of a throttle valve opening controls a start timing of a supply of the hydraulic pressure to the friction engaging element on the basis of an accelerator pedal opening and the throttle valve opening if a shift lever is changed from an advance position to a reverse position or from the reverse position to the advance position.

A control device for a vehicle is provided. The control device includes an electronic control unit that is configured to: exert the torque of an input member on a fixed member and a rotating member such that the fixed member and the rotating member are separated from each other, when the thrust is exerted for making the engagement teeth mesh with each other; estimate an inclination angle of tooth surfaces based on a relative movement amount between the fixed member and the rotating member, and a relative rotational amount between the fixed member and the rotating member; estimate a frictional coefficient of the tooth surfaces based on the inclination angle; and control the thrust of the actuator according to the frictional coefficient.
