  • Publication number: 20240083259
    Abstract: An electric vehicle including a motor as a driving source includes: an accelerator; a pseudo shifter mimicking a gear changing operation; a pseudo clutch mimicking a clutch operation; a detector detecting an operation mode performed on each of the accelerator, pseudo shifter, and pseudo clutch by a driver, and a rotation speed of a driving wheel; a reaction force generator generating a reaction force in the pseudo shifter in response to a driver operation performed thereon; and a controller determining the reaction force. The controller includes a processor and a memory coupled thereto. The processor calculates a virtual differential rotation speed that is based on a virtual engine rotation speed, mimicking an engine rotation speed when the driving source is assumed as being an engine, and the rotation speed based on a detection result of the detector, and determines the reaction force based on the virtual differential rotation speed.

  • Patent number: 11920841
    Abstract: An air-conditioning apparatus includes a main circuit in which a compressor, a flow switching device, an indoor heat exchanger, a pressure reducing device, and a plurality of parallel heat exchangers connected in parallel with each other are connected by pipes, a bypass pipe, a flow control device provided to the bypass pipe and configured to adjust a flow rate of refrigerant flowing through the bypass pipe, an evaporating pressure sensor configured to measure an evaporating pressure of the refrigerant, and a controller. The air-conditioning apparatus is configured to operate in a normal heating operation mode and a heating-defrosting operation mode. When an operation associated with the normal heating operation mode is switched to an operation associated with the heating-defrosting operation mode, the controller adjusts an opening degree of the flow control device using the evaporating pressure in the parallel heat exchanger and a driving frequency of the compressor.
