This disclosure generally relates to an electric vehicle. More specifically, this disclosure describes a motor control system for an electric vehicle that activates and deactivates a hill hold assist mode and a hill start assist mode for the electric vehicle. The hill hold assist mode is used to help ensure the electric vehicle remains stationary while stopped on an uphill incline. Likewise, the hill start assist mode is used to help a rider of the electric vehicle start the electric vehicle moving again once it is stopped on the uphill slope.

SYSTEMS AND METHODS FOR INTELLIGENTLY ENGAGING MULTIPLE BRAKES

A system for multiple brakes intelligently controlled by a single brake input on a personal mobility vehicle. By determining a front and rear brake differential based on the position and weight of the rider as well as the environmental and vehicle conditions, the system may reduce the risk of the vehicle skidding or tipping due to over-braking. In some embodiments, a rider may use a single brake lever to indicate a desire to brake and the system may make determinations about how to apply a combination of mechanical and electrical brakes to front and back wheels. By applying different braking systems based on a combination of controls and sensors, the system may improve user experience and user safety, especially for inexperienced riders.

Control apparatus for vehicle drive-force transmitting apparatus
10865856 · 2020-12-15 · ·

A control apparatus for a drive-force transmitting apparatus that defines a first drive-force transmitting path that is to be established by engagements of a first frictional engagement device and a dog clutch and a second drive-force transmitting path in which a lower gear ratio is provided than in the first drive-force transmitting path. In a second running mode with the second drive-force transmitting path being established, the control apparatus places the dog clutch in a released state when a vehicle running speed is higher than a first speed value, and places the dog clutch in an engaged state when the running speed is not higher than the first speed value. Further, in the second running mode, the control apparatus inhibits the dog clutch from being switched to the released state when an accumulated heat quantity in a synchromesh mechanism of the dog clutch is larger than a first quantity value.

A through the road (TTR) hybridization strategy is proposed to facilitate introduction of hybrid electric vehicle technology in a significant portion of current and expected trucking fleets. In some cases, the technologies can be retrofitted onto an existing vehicle (e.g., a trailer, a tractor-trailer configuration, etc.). In some cases, the technologies can be built into new vehicles. In some cases, one vehicle may be built or retrofitted to operate in tandem with another and provide the hybridization benefits contemplated herein. By supplementing motive forces delivered through a primary drivetrain and fuel-fed engine with supplemental torque delivered at one or more electrically-powered drive axles, improvements in overall fuel efficiency and performance may be delivered, typically without significant redesign of existing components and systems that have been proven in the trucking industry.

Electric vehicle

In an electric vehicle, a power supplier includes a software type condenser charging circuit and a hardware type condenser charging circuit. The software capacitor charging circuit operates when a controller controls the software type condenser charging circuit while monitoring a voltage between opposite ends at an initial charging stage. The hardware type condenser charging circuit is operated when the controller controls the hardware type condenser charging circuit without monitoring the voltage between the opposite ends of the DC-link condenser or by direct switching manipulation of a user.
