An electronic control unit (ECU), also known as an electronic control module (ECM), is an embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a car or other motor vehicle.
Tesla Autopilot, an advanced driver-assistance system for Tesla vehicles, uses a suite of sensors and an onboard computer. It has undergone several hardware changes and versions since 2014, most notably moving to an all-camera-based system by 2023, in contrast with ADAS from other companies, which include radar and sometimes lidar sensors.
At the beginning of the self-driving car program, they used a $75,000 lidar system from Velodyne. [59] In 2017, the cost decreased approximately 90 percent, as Waymo converted to in-house built lidar. [60] Waymo has applied its technology to various cars including the Prius, Audi TT, Fiat Chrysler Pacifica, and Lexus RX450h.
Tesla Autopilot in operation, 2017. Tesla Autopilot is an advanced driver-assistance system (ADAS) developed by Tesla that amounts to partial vehicle automation (Level 2 automation, as defined by SAE International).
The earliest electronic systems available as factory installations were vacuum tube car radios, starting in the early 1930s.The development of semiconductors after World War II greatly expanded the use of electronics in automobiles, with solid-state diodes making the automotive alternator the standard after about 1960, and the first transistorized ignition systems appearing in 1963.
For the 1990 season, all teams using the Ilmor Chevy Indy V8 were provided a redesigned Gen-3 system and it won 15 poles, 16 wins including the 1990 Indianapolis 500, with 17 races in the IndyCar World Series. To prove the system, the components were used with GM engines in the Trans-Am Racing series during 1989.
A second cyber incident at data provider CDK Global, whose software is used at 15,000 auto dealers, continued to slow operations to a near-standstill Thursday at US and Canada dealerships, the ...
A challenge to installing a computer in a car is the power supply. Energy is supplied as a nominal 12 VDC in cars or 24 VDC in some trucks. The voltage varies according to whether the engine is on or off since the battery generally delivers 12V, while the generator supplies more. There can be peaks, and at ignition time the supply current drops.
