摘要： A method for controlling brake pressure during a shift of a vehicle out of park may include determining that a first status condition is met when the vehicle is in park with an electric parking brake applied, determining that a second status condition is met when the vehicle is not moving, responsive to detecting a shift of the vehicle out of park when the first and second status conditions are both met, directing a build-up of brake pressure until a brake pressure target is reached, and holding the brake pressure at the brake pressure target until a release condition is met.

摘要： Data is received from a plurality of sensors mounted on an ADV being held to a standstill. A status of the ADV including a rolling speed of the ADV is detected based on the data from the plurality of sensors. One of a primary brake or a secondary brake is activated, in response to detecting the status of the ADV being a first status including the rolling speed being higher than zero and lower than a first predetermined speed threshold. An electronic parking brake is activated, in response to detecting the status of the ADV being a second status including the rolling speed being higher than the first predetermined speed threshold and lower than a second predetermined speed threshold. An engine brake may be used to reduce the crash damage, and a warning message (e.g., Message-4) may be generated.

摘要： 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.

摘要： A method is provided for operating a motor vehicle including a first driven axle, with which a first electric drive unit and a first brake mechanism are associated, and a second driven axle, with which a second electric drive unit and a second brake mechanism are associated, in a hill hold operating mode, in which the brake mechanisms are configured to brake the two axles with a predetermined brake torque distribution. According to the method, a hill hold requirement for the motor vehicle is identified and a compensation torque distribution to the two axles, provided in relation to the hill hold requirement, in accordance with the predetermined brake torque distribution is determined. The compensation torque is applied in accordance with the compensation torque distribution, and the compensation torque applied by the respectively associated drive unit is replaced with compensation torque applied by the brake mechanism of the respective axle.

摘要： A method for disengaging a parking lock of a dual-clutch transmission of a motor vehicle with at least one drive unit is provided. The method includes, upon detection of an absolute value of a road inclination along a longitudinal axis of the motor vehicle exceeding a predetermined threshold and upon actuation of a selector lever for disengaging the parking lock prior to disengagement of the parking lock, issuing a torque request to the drive unit and closing a power-shifting clutch of the dual-clutch transmission with an engaged gear in a sub-transmission to which the power-shifting clutch is allocated. A torque transferred by the power-shifting clutch as a consequence of closing the power-shifting clutch and the torque request to the drive unit is a relief torque. The torque request to the drive unit and the closed power-shifting clutch are selected to counteract a torque, supported by a parking lock pawl, applying with an engaged parking lock by drive wheels on an output side at the transmission.

摘要： A method for restarting an engine of a vehicle stopped on a grade, comprising the steps of engaging a gear of a transmission through which the engine and wheels of the vehicle are drivably connected mutually, using brake pressure to engage wheel brakes and produce a road gradient wheel torque that holds the vehicle stationary on the grade, initiating an engine restart, operating the engine to produce wheel torque equal to or greater than the road gradient wheel torque, and releasing the brake pressure.

摘要： The present disclosure relates to a shifting control method that improves driving stability by reducing roll-back of a vehicle during the process of shifting on an uphill slope. The shifting control method for a hybrid vehicle includes: determining a degree of roll-back of the vehicle on the basis of a change in the number of revolutions of a transmission input shaft, when power-off down-shifting into a lowest gear is requested; decreasing a disengaging clutch torque, increasing an engaging clutch torque, and increasing a motor torque so that the motor torque follows a desired motor torque, when the degree of roll-back is equal to or greater than a set value; synchronizing a motor speed with an engaging input shaft speed by decreasing the motor torque, when the disengaging clutch torque is equal to or less than a set torque; and finishing the shifting by increasing the motor torque when the synchronization is finished.

摘要： A controller for a vehicle is provided. The vehicle includes an engine, a rotary machine, at least one driving wheel, a first clutch disposed between a power transmission member and the rotary machine, the power transmission member being disposed between the engine and the driving wheel, the first clutch being configured to be switched to an engaged state or a disengaged state, and a second clutch disposed in parallel with the first clutch, the second clutch being a one-way clutch. The controller includes an electronic control unit. The electronic control unit is configured to control at least one of the rotary machine or the first clutch so as to reduce inertia of the power transmission member based on a torsional load acting on the power transmission member.

摘要： The device that generates the friction braking force to decelerate the vehicle estimates the disturbance torque acting on the vehicle. When the accelerator operation amount is equal to or less than the predetermined value and the vehicle is just before the stop of the vehicle, the control device for vehicle causes the friction braking amount to converge to the friction braking amount to the value decided on the basis of the disturbance torque estimated value Td in conjunction with the reduction in the motor rotation speed (speed parameter) proportionate to the traveling speed of the vehicle.
