IPC: H02J50/00
Filed: 2020-05-21
Abstract: This application discloses a wireless charging receiver (1000a), system, and control method, and relates to the field of wireless charging technologies. A receiver coil (Ls) of the receiver (1000a) converts an alternating magnetic field transmitted by a transmitter (1001a) to an alternating current, and delivers the alternating current to a compensation network (200). The compensation network (200) compensates the alternating current, and then delivers the compensated alternating current to a rectifier (H2). The rectifier (H2) rectifies the compensated alternating current to a direct current, and supplies the direct current to a load. The compensation network (200) is a compensation circuit with a current source characteristic, so that the receiver coil (Ls) and the compensation network (200), acting together with the transmitter (1001a), make an input end of the rectifier (H2) a constant current source. During turn-on of the receiver (1000a), a receiver controller (201) controls a switching tube in the rectifier (H2) to be closed, so that the load is bypassed; and then the receiver controller (201) controls the receiver (1000a) to start working. Alternatively, during turn-off of the receiver (1000a), the receiver controller (201) controls a switching tube of the rectifier (H2) to be closed, so that the load is bypassed; and then the receiver controller (201) controls the receiver (1000a) to enter an off state. With the receiver (1000a), the receiver (1000a) and the load can be protected from damage during turn-on or turn-off of the receiver (1000a), thereby improving safety of a wireless charging system.

Abstract: A lateral control error of a steering system of an ADV is determined, which includes iteratively performing following operations for a predetermined time period. Whether the ADV is moving within a predetermined proximity of a current moving direction is determined. Next, whether a road condition of a road on which the ADV is driving satisfies a predetermined road condition is determined. Then, a first steering feedback of the ADV in response to a prior steering control command is measured. Thereafter, the lateral control error is determined based on at least a portion of the first steering feedback over the predetermined time period. Further, a steering command in view of the lateral control error of the steering system is generated. Finally, the steering command is applied to control the ADV to compensate the lateral control error of the steering system.
