The disclosure provides a transmission selector for a vehicle. The transmission selector for a vehicle includes: a transmission selector element including a first switch and a second switch, and a control circuit. When the vehicle speed is equal to or less than a first threshold, the control circuit switches the current gear to D in response to the selection operation received by the first switch, and the control circuit switches the current gear to R in response to the selection operation received by the second switch. When the vehicle speed is equal to or less than the first threshold and the vehicle meets the specified conditions, the control circuit controls the vehicle to switch the current gear in response to a long-press operation whose execution of the selection operation received by the first switch or the second switch reaches a first specified time.

Systems and methods are provided for controlling a transmission associated with a vehicle. The method includes receiving a neutral range selection for the transmission, and receiving a temperature and a pressure of a lubricant associated with the transmission. The method includes receiving a speed of an input shaft associated with the transmission, and determining, by a processor, based on the temperature and the speed of the input shaft, a pressure threshold value for the lubricant. The method includes outputting, by the processor, one or more control signals to command the transmission to a one clutch neutral state in which one clutch of a plurality of clutches associated with the transmission is engaged based on a comparison of the pressure threshold value to the pressure of the lubricant.

Disclosed is a method for determining a position of a motor vehicle by means of a location device of the motor vehicle. First, a first position (x.sub.1) related to an installation point of the location device in the motor vehicle is determined. In order to determine a position suitable for controlling the motor vehicle, with reference to the said first position (x.sub.1) a second position (x.sub.2) related to a center of gravity of the vehicle is determined, in that the first position (x.sub.1) is offset by a distance (a) between the said installation point of the location device and the center of gravity of the vehicle.

Methods for controlling a transmission of a vehicle are provided. Such methods include establishing a desired speed profile for the vehicle when travelling along a road segment. performing a plurality of simulations, each of a vehicle response, in the road segment, to a respective gear control action, wherein the gear control action differs from one simulation to another, wherein the simulations include an aim to keep the speed on the speed profile, or within one or more established limits of deviations from the speed profile, determining costs for the simulated vehicle responses, selecting, in dependence on the determined costs, one of the gear control actions, controlling the transmission with the selected gear control action.

A control method of an electric vehicle is provided. The method includes generation of a virtual sensation of gear shifting of an electric vehicle capable of freely, directly changing and adjusting variables related to generation of the virtual sensation of gear shifting to provide drivers with preferred virtual sensation of gear shifting. The virtual sensation of gear shifting is generated according to driver's driving input values and vehicle conditions based on variable values related to the virtual sensation of gear shifting generation preset by a driver to simulate multi-speed gear shifting that the driver may sense when shifting in a vehicle having a multi-speed transmission, while driving an electric vehicle without the multi-speed transmission.

An apparatus and a method for controlling a transmission of a vehicle include an agent that determines a gear stage of the vehicle based on driving information of the vehicle, shape information of a road, and/or operation information of a driver, and include a controller that performs a reward with respect to the determination of the agent and controls the transmission of the vehicle based on the gear stage determined by the agent.

A method and a system for controlling a gear of the two-speed gearbox and a vehicle is provided. The method for controlling a gear of a two-speed gearbox includes: determining a first target gear of the gearbox reflecting a current driving demand of a user according to a current vehicle-speed; and performing a gear intervention control of the gearbox based on at least one of the following aspects: position information of a drive gear-lever, a rotation-speed of a drive motor of a vehicle, and gear fault information of the gearbox, to shift the first target gear of the gearbox to a second target gear of the gearbox that matches with real-time operation conditions of the vehicle.

An apparatus for diagnosing an automatic transmission for detecting abnormality during driving of a vehicle includes a G-sensor configured to measure a vibration signal including a longitudinal vibration signal, a status detection unit configured to obtain the vibration signal of the G-sensor and status data of transmission and engine sensors of the vehicle, and a controller configured to check an operational element for each shifting operation by using a current shift-stage, a target shift-stage, and a shifting time detected as the status data, measure the longitudinal vibration signal of the G-sensor to calculate fluctuation level of the longitudinal vibration signal for each operational element, and determine a shift shock event when a longitudinal vibration signal value after adjustment based on driving acceleration of the vehicle exceeds a reference value.

Techniques related to vehicle operation. A processor determines that at least one condition is met related to a vehicle. In response to the at least one condition being met, the processor generates a natural language output having a query. The processor determines that an affirmative response to the query is received and causes a downshift of a transmission of the vehicle in response to the affirmative response.

Methods and system are described for changing a driveline gear range from a higher gear range to a lower gear range. The driveline may include two electric machines and four clutches in a four wheel drive configuration. The methods and systems permit a driveline to change from a higher gear range to a lower gear range without stopping a vehicle.
