Application point of 6in1 sensor for auto lawnmower
- 6-axis detection enables high-accuracy detection for overturning caused by tilting, speeding, or steps during auto-cruising
- Self-diagnosis function in all 6 axes can avoid unsafe events in advance
- Conformance to ISO26262 is best suited not only for automotive use but also for industrial mobility automation
Adoption effects of 6in1 sensor to auto lawnmowers
Effect (1) 6-axis detection enables accurate detection of overturning caused by tilting, speeding, steps, etc., during auto-cruising
An auto lawnmower detects its motion direction, position information, obstacle, etc., by using a camera, Lidar, GNSS, etc., but by detecting its angular speed and acceleration using a 6in1 sensor, additional accurate information required for auto-cruising such as tilt and speed can be obtained. In addition, when the lawnmower is overturned by a step, etc., its rotating blade needs to be stopped, and the 6in1 sensor can accurately detect motions including overturning in addition to auto-cruising.
【Point】
- 6 axes in a single package accurately detect lawnmower's motions such as auto-cruising, overturning, etc., thereby contributing to the safety of the system.
Effect (2) Built-in self-diagnosis function in all 6 axes can avoid unsafe incidents in advance.
As mentioned, when the lawnmower overturns, its blade motion needs to be stopped. If the sensor fails and the overturning is not detected, the bare blade continues to rotate. Because the 6in1 sensor is equipped with a self-diagnosis function, the sensor notifies the failure to the system and an unsafe event can be avoided in advance.
【Point】
- Because the self-diagnosis function is built into every axis, unsafe events caused by sensor failure can be avoided in advance, thereby contributing to the system safety.
Effect (3) Conformance to ISO26262 makes the sensor suited not only for automotive applications but also for industrial mobility automation
Because automatic lawnmowers can also be used near public roads or sidewalks, components used for such equipment are recommended from automotive components. Because the 6in1 sensor conforms to ISO26262 (ASIL B(D), with actual use records as an automotive component, this product can be selected in confidence by industrial equipment users.
【Point】
- Conformance to ISO26262 makes application not only for automotive use but also suited for industrial mobility automation such as auto lawnmowers.
