Based on the provided reference, Tesla vehicles utilize 12 long-range ultrasonic sensors strategically placed around the car.
Understanding Tesla's Ultrasonic Sensors
These sensors are a key component of the vehicle's sensing system, designed to detect objects in the immediate vicinity. They are described as long-range, capable of sensing everything within a specific distance from the vehicle.
Key Characteristics of Tesla's Ultrasonic Sensors
- Type: Long-range ultrasonic sensors
- Quantity: 12 sensors positioned around the car
- Range: Sense objects within 16 feet (approximately 4.8 meters) away from the vehicle.
- Function: Detect nearby objects to assist with features like parking or avoiding low-speed collisions.
- Vulnerability: Their function can be impaired if they are covered by debris.
These sensors work by emitting ultrasonic sound waves and measuring the time it takes for the waves to reflect back after hitting an object. This data allows the car's system to determine the presence and distance of surrounding obstacles.
Sensor Details
| Feature | Description |
|---|---|
| Type | Ultrasonic |
| Number | 12 |
| Placement | Around the vehicle |
| Range | Up to 16 feet (approx. 4.8 meters) |
| Function | Detect nearby objects |
| Known Issue | Affected by debris |
The reference also mentions "A high-precision, digitally-controlled electric assist braking system," which suggests that data from these or other sensors could potentially be used to inform or control braking actions, particularly at close ranges or low speeds. However, the primary description of the sensor itself focuses on its detection capabilities and physical properties.
It's important to keep the sensors clear of obstructions like mud, snow, or ice to ensure they function correctly and can accurately detect the environment around the vehicle.
