Abstract:
Manufacturers and original equipment manufacturers provide vehicles that include various components and systems that operate to provide safe, environmentally conscious transportation compliant with local, state, and federal requirements. Each of the components or systems may include a nontransitory storage media containing data indicative of an authentication code specific to the respective component or system. Authentication data may be communicated from each of the nontransitory storage media on a vehicle to a control system where the authentication data is compared to one or more defined criteria. If the one or more criteria confirm the validity of the authentication data supplied by the components or systems, full operation of one or more vehicular systems is permitted. If the one or more criteria fail to confirm the validity of the authentication data supplied by the components or systems, the operation of at least one vehicular system is at least partially inhibited.
Abstract:
An image capturing method has: providing an image capturing area on a display screen of a user device; providing an indication area in the image capturing area; identifying each license plate in the indication area; calculating a license plate area of said each license plate in the indication area; calculating a center point difference from a center point of said each license plate in the indication area to a center point of the indication area; marking a license plate that has a license plate area larger than half of a largest license plate area and has a smallest center point difference; and capturing an image including the marked license plate in the image capturing area.
Abstract:
The present disclosure provides a power assisted electric bicycle, a transmission device and a control method. The power assisted electric bicycle includes a body, a wheel, a torque sensor, a motor and a controller. The torque sensor is configured to output a plurality of torque signals corresponding to a pedal force. The controller is configured to: receive the torque signals from the torque sensor; compute and determine a first period according to a speed of the power assisted electric bicycle at a first time point; obtain a first maximum value of the torque signals in the first period that ends at the first time point; and, set a first torque output of the motor according to the first maximum value corresponding to the torque signal.
Abstract:
A torque-speed curve or data of load that is used as a standard to determine an external condition in which an electric vehicle is operating such as incline or no incline, head wind or no headwind, high temperature or low temperature. The system compares samples of actual torque-speed of load data to the standard. Based on the comparison, the system determines the external condition (going up a hill, traveling into a headwind, operating at high temperature) or an abnormal operation of the vehicle powertrain, for example, low tire pressure, elevated friction, wheels out of alignment. Based on the determination, the system takes an action to govern a maximum torque output of the motor to control temperature of the vehicle battery; to raise a wind deflector; to govern maximum speed of the vehicle to reduce danger resulting from low tire pressure, elevated powertrain friction or out of alignment wheels; or to initiate an indication of abnormal conditions.
Abstract:
The present disclosure relates to methods and associated systems for operating a battery exchange station. The present method includes (1) receiving a ratio associated with a plurality of vehicles served by the battery exchange station; and (2) based on the ratio, storing different sets of information in memories associated with the batteries respectively, in accordance with received ratio.
Abstract:
The present disclosure is directed to methods, devices, and systems for playing audio signals associated with an electric in vehicle. The method includes, for example, (1) determining a speed of the electric vehicle; (2) receiving, from a memory, a plurality of sound frequency characteristics corresponding to the determined speed of the electric vehicle; and (3) generating an audio signal segment corresponding to the received sound frequency characteristics by a speaker of the electric vehicle. The sound frequency characteristics include a plurality of segments. Each of the segments includes an amplitude of a number of frequency characteristics in a sound produced by a powertrain assembly (e.g., an electric motor) in a speed range.
Abstract:
A wiring device includes a plurality of trenches and a plurality of channel sets. The trenches at least include a first trench, a second trench and a third trench, bottoms of which are respectively located at different height positions. Each of the channel sets at least includes a first channel, a second channel and a third channel. The first channels penetrate the wiring device from an outer sidewall thereof to the first trenches, respectively, the second channels penetrate the wiring device from the outer sidewall thereof to the second trenches, respectively, and the third channels penetrate the wiring device from the outer sidewall thereof to the third trenches, respectively. The wiring device has the advantages of a simple structure and a low cost for molding and manufacturing, and is suitable to perform winding by a manual or automatic machine and thus can prevent first output wires of the coil windings with in phase or out of phase from entangling or knotting with each other.
