摘要： The present disclosure provides a method for monitoring a motion status of a vehicle, a related chip, and a system. The method includes: obtaining N acceleration values in a first axial direction collected from N times sampling and a maximum acceleration change value within a preset time period; and obtaining N acceleration values in a second axial direction collected from N times sampling and a maximum acceleration change value within the preset time period; determining whether the vehicle is in motion or in a first stationary state based on the acceleration values in the first and second axial direction; and in response to the vehicle being in the first stationary state, further determining whether the vehicle is in motion or in a second stationary state based on the maximum acceleration change values in the first and second axial direction.

摘要： The present application discloses a data acquisition method, a microprocessor and an apparatus with storage function. The method may include: a request information for obtaining a target information may be received. The request type of the request information may be an instruction request or a data request. The instruction cache and the data cache may be queried respectively, to determine whether the target information matching with the requested information exits in the instruction cache and the data cache. If the target information exists in another cache that does not match with the request type of the request information, then the target information may be returned from the cache that does not match with the request type of the request information. The present application may physically separate the instruction cache and the data cache, thereby improving the data acquisition efficiency.

摘要： A power amplifier includes: at least two first bridge type amplifying circuits and at least two second bridge type amplifying circuits; the negative pole of the first load of each first bridge type amplifying circuit is respectively coupled to the positive stage of the second load of each second bridge type amplifying circuits through a gating circuit. When both a first input signal input into one of the at least two first bridge type amplifying circuits and a second input signal input into one of the at least two second bridge type amplifying circuits are less than a preset threshold, the gating circuit is turned on, so that the one of the at least two first bridge type amplifying circuits and the one of the at least two second bridge type amplifying circuits can share load current by the gating circuit.

摘要： The present disclosure provides a left and right wheel determination method, a wheel pressure monitoring chip and system, and related apparatuses. The left and right wheel determination method includes: obtaining a time duration for a wheel to rotate for a predetermined number of revolutions after the wheel being detected as rotating; sampling centrifugal acceleration and tangential acceleration of the wheel within the time duration; determining an overrun-lag relationship between the centrifugal acceleration and the tangential acceleration of the wheel based on a serial number of a sampling time-point corresponding to the centrifugal acceleration and a serial number of a sampling time-point corresponding to the tangential acceleration; and determining the wheel to be of a left wheel or a right wheel based on the overrun-lag relationship between the centrifugal acceleration and the tangential acceleration of the wheel.

摘要： The present disclosure provides a method based on a motor stall protection and a motor stall protection apparatus. The method may includes: obtaining a rotational speed of a motor rotor and an output current of a motor stator; performing a pre-stall protection in response to the rotational speed being less than a first rotational speed threshold and the output current being greater than a first current threshold, the performing a pre-stall protection comprises obtaining a power module temperature, a stall decision value and a first current accumulation value; performing the stall protection in response to the first current accumulation value obtained being greater than the stall decision value. The method based on the motor stall protection provided in the present disclosure may determine a timing of performing the stall protection by periodically comparing the first current accumulation value and the stall decision value.

摘要： The present disclosure provides a composite sensor and a manufacturing method thereof. The composite sensor includes: a first substrate and a second substrate configured to be laminated with the first substrate; a pressure sensor located on the first substrate and configured to sense a change in external pressure; and an acceleration sensor located on the second substrate and configured to sense a change in acceleration. A pressure film of the pressure sensor is configured to be spaced from the second substrate to form a pressure cavity, and a proof mass of the acceleration sensor is configured to be spaced from the first substrate to form a first anti-collision cavity. The present disclosure may reduce the chip area and reduce mutual interference.
