Detroit - Tesla Motors is planning improvements to its semi-autonomous autopilot system after a fatal crash earlier in 2016.
Tesla CEO Elon Musk wrote in a Tweet on Wednesday (August 31) that a software update will be released in a few weeks.
Over-the-air delivery
Musk says a software update will make "major improvements" to Autopilot, including more advanced processing of radar signals. Software updates are delivered over the air to Tesla owners.
Tesla's Autopilot system can maintain a set speed, keep the car within its lane and brake automatically. Radar helps the car see things that may be blocked to cameras in bright sunlight or bad weather.
