FRANKFURT ”“ Advanced driving assistance functions are getting a big boost from improved connectivity, a senior Robert Bosch executive said Wednesday, but full autonomous driving will take a while to become a reality.

"Amid all the euphoria about autonomous driving, we believe it will happen after 2020," said Dirk Hoheisel, a Bosch board member in charge of chassis systems control, car multimedia and automotive electronics. Major car makers, including Mercedes and Audi, have said driverless driving could be possible before the end of the decade.

Addressing the Mobility 3.0 conference here, Hoheisel said barriers to autonomous propulsion are regulations that currently still forbid driverless driving, the lengthy processes involved in introducing new automotive technologies and the absence of standardized testing procedures.

"The key lies in how we implement new software and development and how we introduce modular hardware and modular test procedures," Hoheisel said. "There's a lot we have to do."

Hoheisel cited progress in several technologies that will be part of an autonomously driven vehicle. They include automated parking and other sensor-driven technologies.

But the Bosch executive noted that, as cars connect to other cars and to the infrastructure around them,  faster mobile connectivity will be required. Addressing the necessary fast response time for effective car-to-x communication, Hoheisel said: "With LTE and fifth-generation mobile technology  the required latency will be available."
