Alps Electric Develops Dual Output Brake Pedal Position Sensor
2018-09-05 | 返回TOKYO, September 5, 2018 – Alps Electric Co., Ltd. (TOKYO: 6770; President: ToshihiroKuriyama), a manufacturer of high-quality electronic components, has developedthe “RD1030211” Dual Output Brake Pedal Position Sensor, enabling voltage output toboth a vehicle’s brake lights and its regenerative braking system.
According to research conducted by LMC Automotive, the share of electric,plug-in hybrid and fuel cell vehicles on the road is expected to rise to about50% by 2030, as these vehicles continue to spread, particularly in markets suchas China, where development is progressing at a rapid pace.
These next-generation automobiles employ regenerative braking systems thatconvert the turning of the wheels as they slow down into electrical energy tobe used to propel the vehicle. For regenerative braking to be efficient, thesystem requires information about how far the brake pedal is pushed in, butconventional single-output sensors have been unable to provide the datasimultaneously with output used to switch on brake lights, placing restraintson design carried out by end-product manufacturers.
In light of these circumstances, Alps Electric developed RD1030211, operating within a temperature range from -40°C to +85°C, with a detection angle of 80° and offering an operating life of 1,000,000 cycles. Analog sensing is retained for the dual-output product, having been popular with earlier single-output models.
As can be seen in the picture below, installation is less work as any positional deviation is electronically calibrated, eliminating the need for the kind of physical adjustments required with switch sensing and therefore contributing to labor saving in customer production lines. The sensor is ideal for regenerative braking systems, brake light activation and cruise control deactivation, thereby contributing to compact design of next-generation vehicles.
