ACC(Adaptive Cruise Control) prototype vehicle developed by ADC, a Leica subsidiary. It is equipped with ACC marketed in Japan, with braking control added.
ACC, which has been sold in Japan, has speed maintainance with throttle and transmission control. Due to minimal degree of deceleration, headway is set at roughly 2.0 seconds. In this demonstration system, headway is approximately 1.4 seconds (range of 1.0 to 2.0 seconds available depending on volume), for practicality in actual driving.
Due to Leica’s tradition as an optical equipment maker, the company believes that it should provide driving support with environmental data detection feature that approximates human vision. It believes that the range of support that humans can tolerate is close to that range that can be detected by human vision and that detection with radar that humans cannot detect is beyond human acceptance. For this reason, it employs a laser radar, according to a demo vehicle guide. |
