Publication number: 20230158915Abstract: A charge control device is mounted on a vehicle to which external power for charging a storage battery is supplied from an external power supply. The charge control device has an acquisition part, a calculation part, and an output part. The acquisition part acquires a detection result of a physical quantity sensor that detects a physical quantity related to charging of the storage battery. The calculation part changes a target value of the physical quantity when a charge amount of the storage battery is equal to or greater than a target charge quantity and a difference between the target value of the physical quantity and the detection result is lower than a predetermined value. The output part outputs an instruction signal including an instruction to control an external power based on a target value to the external power supply.Type: ApplicationFiled: January 23, 2023Publication date: May 25, 2023Applicant: DENSO CORPORATIONInventors: Bo ZHOU, Junmin CAO

Patent number: 10491437Abstract: A circuit for demodulating an input signal is described. The circuit may be configured to demodulate signals modulated with amplitude-based modulation schemes, such as amplitude shift keying (ASK). The demodulator may comprise a clock extractor configured to generate a clock signal in response to receiving an amplitude-modulated input signal, a phase shifter configured to generate a sampling signal by phase-shifting the clock signal by approximately ?/2, and a sampler configured to sample the input signal in correspondence to one or more edges (such as one or more falling edges) of the sampling signal. In this way, the amplitude-modulated input signal may be sampled at its peak, or at least near its peak, thus ensuring high signal fidelity.Type: GrantFiled: October 6, 2017Date of Patent: November 26, 2019Assignee: MEDIATEK Singapore Pte. Ltd.Inventors: Junmin Cao, Hon Cheong Hor, Tieng Ying Choke

Patent number: 9421871Abstract: A motor controller includes an inter-vehicle sensor detecting an inter-vehicle distance between an own vehicle and a front vehicle, a speed sensor detecting a speed difference between a speed of the own vehicle and a speed of the front vehicle, an accelerator sensor detecting an accelerator pressing quantity, and a control portion controlling a regeneration torque of the motor based on the inter-vehicle distance, the speed difference, and the accelerator pressing quantity. When the control portion determines that the accelerator pressing quantity is less than or equal to a predetermined pressing quantity, the control portion determines that a speed-reduction request is generated. When the control portion determines that the inter-vehicle distance is no more than a first predetermined distance and when the own vehicle is in an approaching state, the control portion increases the regeneration torque of the motor, so as to generate a regeneration braking force.Type: GrantFiled: September 9, 2015Date of Patent: August 23, 2016Assignee: DENSO CORPORATIONInventor: Junmin Cao

Patent number: 9333969Abstract: A Hybrid vehicle has an internal combustion engine, a first motor-generator, i.e., MG, a second MG, a battery section, and a control section. The control section performs first control which transmits power of the first MG to a drive shaft. The control section performs second control which starts the internal combustion engine by generating torque to the internal combustion engine using difference of rotational speeds of the first MG and the second MG, when the battery section fails while performing the first control. In the second control, the control section controls the second MG to generate electric power for driving the first MG. It is possible to provide a hybrid vehicle capable of starting the internal combustion engine even if the battery section becomes abnormal.Type: GrantFiled: January 19, 2015Date of Patent: May 10, 2016Assignee: DENSO CORPORATIONInventor: Junmin Cao
