How the Technology Works

Hazard Enhanced Location Protocol (HELP) - patented by Tesla Inc. accident prevention software. Its task is to warn passing vehicles about a faulty car.

The LED lights transmit a fault signal from the light switch or controller to the vehicle's telematics system. It collects data on the machine's state online through sensors and space satellites. Further, the navigation systems distribute the danger alert to oncoming vehicles. This technology reports faulty cars from the driver's vision field on the motorway.
The protocol is being developed jointly with Emergency Safety Solutions. First, it will be implemented in models released in North America. The standard complies with US law and received National Highway Traffic Safety Administration (NHTSA) approval in January 2021. Similar decisions are also expected in Europe and Asia. The system is activated on electric vehicles after updating the installed software or after flashing, so it will require a little cost.
The new intelligent early warning technology consists of 2 components:
● Emergency lighting with increased flashing frequency.● Digital alert of oncoming cars is sent to applications via GPS navigation. 
When this function is enabled, an alert about a damaged electric car will automatically appear on the screen in approaching cars. With early warning, the driver has a few minutes to react and avoid colliding with the disabled vehicle. As a result, reducing the number of deaths in car accidents will be possible.

Advanced Emergency Lights

The warning light is a visual warning to nearby vehicles using an alarm. The flash is repeated 1-2 times per second in standard lights. This standard has stayed the same since 1951, although it was developed for incandescent lamps and old control relays.
HELP technology involves modernizing the alarm system by introducing lamps that flash at higher frequencies (4-5 times per second). Their brightness reaches 240 cd/m2 at night and 420 cd/m2 during the day. Such lighting is considered more efficient because it attracts the attention of drivers better. If spotted in advance, there is plenty of time to change lanes, slow down, avoid the damaged vehicle, or stop. Thus, it will be possible to prevent accidents, which means reducing the number of road injuries and deaths.

Using the Internet for Alerts

Digital Emergency Notification is an early warning feature that helps prevent a collision. After turning on the signal lights, the emergency lighting command must be selected on the touch screen. Further, with the help of HELP, a message or sound signals about the need to be careful on the road are sent to oncoming cars.
Alerts come quickly thanks to the GPS satellite navigation system and the mobile applications Google Maps, Apple CarPlay, and Waze.

The technology warns of a vehicle standing on the side of the road. It does not matter whether it is in the field of view of oncoming drivers. The only requirement is that they must include options to accept such warnings. Otherwise, messages will not be available.

System Activation

The HELP protocol is enabled manually or automatically. It activates on its own in the following situations:
● Airbags deployed.● Emergency sensors or other sensor devices are turned on.● There are severe malfunctions in the transmission.● Tires ruptured during an accident.● There was a failure in the control system.
Manual activation is available for parked vehicles or after applying the parking brake. This function starts working after confirming the control system or pressing the button next to the alarm.
