Arrangement of a parking lock in a vehicular transmission
A parking lock in a vehicle transmission includes a locking mechanism for locking and releasing a parking interlock gear (1) and an actuating unit. The actuating unit is coupled via a coupling mechanism to the locking mechanism in order to actuate the locking mechanism between an interlock position and a release position of the parking interlock gear (1). The parking lock is arranged on an intermediate plate (2) in a housing of the vehicle transmission.
POWERTRAIN TO FRICTION BRAKE STANDSTILL HANDOFF FOR ONE PEDAL DRIVE
A method for controlling a vehicle includes monitoring the vehicle speed for a first threshold in conjunction with a driver request for negative torque, after which the method comprises increasing a friction braking ratio. The method further comprises monitoring the speed of the vehicle for a second threshold, wherein the second threshold is lower than the first, after which the method comprises solely using the friction braking for braking holding torque.
BRAKE ASSIST DURING VEHICLE ONE PEDAL DRIVE
A vehicle includes friction brakes, an electronic park brake system, and controllers. The controllers, responsive to the vehicle coming to a stop, and the vehicle being on plug, a driver door of the vehicle being open, or a driver seatbelt being unbuckled, issue a standstill friction brake request for the friction brakes and an electronic park brake request for the electronic park brake system. The controllers also, responsive to engagement of the electronic park brake system, discontinue the issue of the standstill friction brake request.

AGGREGATING BRAKING TORQUE DURING ONE-PEDAL DRIVE MODE
A vehicle includes a powertrain having an electric machine configured to power driven wheels, an accelerator pedal, and friction brakes. A vehicle controller is programmed to, with the vehicle being in a one-pedal driving mode: in response to a braking torque capacity of the powertrain exceeding a target braking torque that is based on a position of the accelerator pedal, command a torque, that is equal to the target braking torque, from the powertrain such that the vehicle is slowed using the powertrain without application of the friction brakes, and, in response to the braking torque capacity of the powertrain being less than the target braking torque, command torques from the powertrain and the friction brakes such that the target braking torque is satisfied and the vehicle is slowed using the powertrain and the friction brakes.
Working vehicle
A working vehicle includes a traveling clutch to be switched between an engaging state and a disengaging state, a brake to brake the traveling device according to an operation of a brake operator, and a controller to perform a braking control to perform the braking, and an auto-switching controller to switch the traveling clutch from the engaging state to the disengaging state. The controller performs a first processing to switch the traveling clutch from the engaging state to the disengaging state when the brake operator is operated in a case where the auto-switching control is valid and a vehicle speed is less than a threshold, and a second processing to prevent the traveling clutch from being switched from the engaging state to the disengaging state even when the brake operator is operated in a case where the vehicle speed is equal to or higher than the threshold.
UTILIZATION OF BRAKES AND TRANSMISSION SYSTEM TO AFFECT STEERING OF A VEHICLE AND METHOD THEREOF
A method of controlling a vehicle during a braking operation includes providing a first and a second brake actuator, a brake input device, a steer input device, and a cross-drive transmission having two outputs and a controller. The method includes detecting a first output speed at the first output and a second output speed at the second output, and receiving a brake input request and a steer input request. The method also includes determining a differential output speed based on the first output speed and the second output speed, and comparing the differential output speed to a first threshold, the brake input request to a second threshold, and the steer input request to a third threshold. The method includes determining the first or the second output is locked during the braking operation, and controlling the first or the second brake actuator based on which output is determined to be locked.
Work vehicle
Provided is a work vehicle having a compact braking device. The work vehicle includes a drive shaft part to which power generated by a power source is transmitted and which transmits the power to drive wheels via a differential device, and a drive shaft braking mechanism which generates a braking force on the drive shaft part when a brake pedal is depressed.
METHOD AND SYSTEM OF CONTROLLING BRAKING OF VEHICLE
A method of controlling braking of a vehicle is provided. When a disconnector is disconnected and an auxiliary drive wheel is separated from a driving system, vehicle braking is performed with regenerative braking by a primary drive wheel motor during braking. Subsequently, the disconnector is connected based on a vehicle stability state, and then, braking is performed simultaneously on the auxiliary drive wheel and a primary drive wheel.
