Vehicle and coasting feedback control method for the same

The present disclosure discloses a vehicle and a coasting feedback control method for the same. The coasting feedback control method includes the following steps: detecting the current speed of a vehicle, the depth of a braking pedal of the vehicle, and the depth of an accelerator pedal; and when the current speed of the vehicle is greater than a preset speed, both the depth of the braking pedal and the depth of the accelerator pedal are 0, and the current gear of the vehicle is gear D, when the vehicle is not in a cruise control mode and an anti-lock braking system of the vehicle is in a non-working state, controlling the vehicle to enter a coasting feedback control mode, where when the vehicle is in the coasting feedback control mode, a coasting feedback torque of a first motor generator and a coasting feedback torque of a second motor generator are distributed according to a selected coasting feedback torque curve of the vehicle.

Device and method for selectively operating a motor vehicle in a user-controlled or an automatic driving operation mode

A system for a vehicle operable in a user-controlled driving mode and an automatic driving mode includes a hand-operated control element and a contact sensor configured to detect whether a driver of the vehicle is holding the control element. The system further includes a controller to monitor an alertness of the driver while the vehicle is in the automatic driving mode depending on whether the driver is holding the control element and/or switch operation of the vehicle between the user-controlled driving mode and the automatic driving mode depending on whether the driver is holding the control element.

DETECTING SPROCKET SEGMENT WEAR BASED ON MACHINE DRIVETRAIN DATA
20230196852 · 2023-06-22 · ·

A controller may receive, from a sensor device of a machine, machine drivetrain data indicating a load, on a drivetrain of the machine, over a period of time. The controller may detect, based on the machine drivetrain data, one or more occurrences of a decrease in the load during the period of time. The controller may determine that the one or more occurrences, of the decrease in the load, are unexpected. The controller may detect wear of a component of an undercarriage of the machine based on determining that the one or more occurrences, of the decrease in the load, are unexpected. The controller may cause an action to be performed based on determining the wear of the component.

VEHICLE AND START/STOP METHOD FOR A VEHICLE ENGINE

A vehicle engine start/stop control method includes shifting an automatic transmission to a park or neutral position and auto-stopping the engine in response the automatic transmission being in the park or neutral position for a predetermined period of time that begins with a shift of the automatic transmission to the park or neutral position.

Hybrid electric vehicle, drive control method and device of the same

The present disclosure provides a hybrid electric vehicle, a drive control method and a drive control device of a hybrid electric vehicle. The drive control method includes: obtaining a current gear position of the hybrid electric vehicle and a current electric charge level of a power battery; obtaining a slope of a road on which the hybrid electric vehicle is driving, if the current gear position of the hybrid electric vehicle and the current electric charge level of the power battery meet a preset requirement; and causing a working state of an engine and/or a motor of the hybrid electric vehicle according to the slope of the road on which the hybrid electric vehicle is driving.

Collison avoidance support device and collision avoidance support method

A vehicle (100) includes a support control unit (111) that supports avoidance of a. collision with an object and a support suppressing unit (112) that suppresses the support of the support control unit (111) when a steering angle of the vehicle (100) is equal to or greater than a predetermined angle. The vehicle (100) further includes an intervention limiting unit (113) that determines whether the support suppression of the support suppressing unit (112) is necessary when the steering angle is equal to or greater than the predetermined angle on the basis of vehicle information acquired from the vehicle (100) or a running environment of the vehicle (100) and that limits intervention of the support suppression of the support suppressing unit (112) depending on the determination result.

VEHICLE ACTIVATION SYSTEMS AND METHODS FOR ELECTRIC VEHICLES
20230182576 · 2023-06-15 ·

Methods and systems for activating electric vehicles are provided. One method includes, in response to a first command to activate the vehicle, transitioning the vehicle from an inactive state to a wake state where a controller of the vehicle is activated and the vehicle is prevented from being propelled by an electric motor of the vehicle. The method also includes, in response to receiving a second command to activate the vehicle after receiving the first command, transitioning the vehicle from the wake state to a ready state where the vehicle is permitted to be propelled by the electric motor.

Vehicle with mountable and removable autonomous driving system

A vehicle comprises an autonomous driving system and a vehicle platform that controls the vehicle in response to a command received from the autonomous driving system. In the vehicle, when a first signal indicates an autonomous mode, the vehicle platform performs a shift change requested through a first command only while the second signal indicates a standstill.

Load-based vehicle operating control

A hybrid electric vehicle includes an engine and an electric machine, both capable of providing propulsion power. A clutch is configured to selectively couple the engine to the electric machine. At times, the vehicle may be subject to excessive loads, such as a large amount of weight in the vehicle or the vehicle towing another object. At least one controller is programmed to engage the clutch and start the engine in response to a load of the vehicle exceeding a predetermined threshold and a release of the brake pedal while the vehicle is stopped and in drive. This increases available engine torque prior to vehicle launch in anticipation of an upcoming acceleration demand.

Method of engaging transmission system of a hybrid vehicle

A traction motor of a hybrid electric vehicle drives a primary pump to provide pressurized hydraulic fluid to engage a power flow path of a multi-ratio transmission. To reduce fuel consumption, the motor is maintained at zero speed until a shift lever is moved into a drive position. After a power flow path is established, the motor speed is again reduced to zero until a driver demands torque by pressing an accelerator pedal. While the traction motor is stationary, an auxiliary pump maintains the fluid pressure to keep the transmission power flow path engaged.
