A device for a vehicle including: a memory configured to store mapping data including machine learning data defining a mapping that uses an estimation variable that is a variable indicating a vehicle operation status of the vehicle and a detection value of a sensor detecting an oil temperature of a power transmission device as input variables, and uses an element corresponding to the input variables as an output variable; and a processor configured to: acquire the input variables; use the mapping to acquire the element as the output variable of the mapping corresponding to the input variables; and determine based on the element whether the detection value becomes equal to or higher than a threshold value due to occurrence of an abnormality in the power transmission device or a mode of vehicle operation by the driver of the vehicle.

A motor vehicle has an electronically controllable parking lock and an electronically controllable parking brake, which can be controlled individually or in combination. A device having an electronic control unit and a central operating element associated with the parking lock and the parking brake is provided. When the motor vehicle is at a standstill and the central operating element is actuated, the parking lock and the parking brake can be controlled in a specific type of parking-lock and/or parking-brake activation. In a first specific type, during a first actuation of the central operating element, at least the parking brake is automatically activated first. If the central operating element is then re-actuated within a predefined time window, or if the central operating element remains actuated for a predefined minimum time period, the driver is offered at least one possibility of manually selecting a specific type of parking-lock and/or parking-brake activation.

An assembly includes a thermoelectric tripping device, a flange, and a gland. The thermoelectric tripping device is configured to be detachably coupled with a damper. The thermoelectric tripping device includes an extending arm including a fuse configured to trip at a pre-defined temperature. The flange is configured to be coupled to a surface of the damper. The gland is defined by a pair of fixtures positioned in-line with each other and having a passage configured therewithin to facilitate passage of the extending arm therethrough. A first fixture of the pair of fixtures is configured to be coupled with the flange, and a second fixture of the pair of fixtures is configured to be detachably coupled with the extending arm.

A shifting controller controls a shifting device of a human-powered vehicle and includes a data acquisition interface, a data storage device, and a control unit. The data acquisition interface is configured to acquire a first reference value of a first variable in relation to the human-powered vehicle. The data storage device has stored therein a shifting condition specified by at least one of a direction of change, an amount of change, and a rate of change that are information on a change in the first variable. The control unit includes a processor that is configured to control the shifting device based on a change in the first reference value and the shifting condition.

A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. A controller controls the shift actuator utilizing an actuating pulse and an opposing pulse.
